A case hosts most of the components in a PC and the largest component of a PC too. Thus, it highly affects the overall looks of the whole PC. The most popular form factors of cases nowadays are mid-tower and full-tower, while a small percentage of people is also interested in small-sized cases known as mini-ITX cases. In this article, we will be reviewing the best case for RTX 3090 and 3090 Ti.
The GeForce RTX 3090 was the flagship graphics card from the RTX 3000-series, although RTX 3090 Ti became the new king after its release. The graphics card is known for its massive VRAM size, a large number of cores, and high TDP. It can consume more than 300 watts at full load, which is why most people who buy an RTX 3090 also buy a large-sized case for efficient heat dissipation. A graphics card alone can’t do much for you so you must need some latest gen RTX 3090 motherboards and high-end processors that ditches any possible bottleneck and helps you to get maximum out of your build.
Coming to the cases used these days, CORSAIR, Thermaltake, Cooler Master, and NZXT are the most popular manufacturers these days. Even though full-tower cases are better than mid-tower cases, most of the cases in the market are mid-tower cases because full-tower cases usually cost more than two hundred dollars.

For something like RTX 3090, we recommend buying a full-tower case. The reason is that you will be able to fit more fans in a full-tower case, and the temperatures of your graphics card and your processor will be lower. It is also important to note that the performance of mesh-front cases is better than glass-front cases, as glass restricts the airflow.

The 8 Best Case for RTX 3090 Reviews
Lian Li O11 Dynamic Xl
Reasons to Buy
- The Aluminum chassis and glass panels make an excellent combo.
- Great set of IO options on the front panel.
- Can house up to three 360mm AIOs.
- E-ATX motherboards are supported out of the box.
- Magnetic intake dust filters overall fans.
Reasons Not to Buy
- Most board don’t come with multiple USB 3.0 headers or lacks a USB 3.1 Type-C header.
- A few more Velcro strips will be good.
Lian Li O11 Dynamic Xl is slightly expensive but targeted towards enthusiast and made for those users who wants nothing but the best. This case didn’t get much attention when it was released, but it came into the mainstream when Lian Li collaborated with an overclocker in Germany, Der8auer. Based on our reviews and experience, it’s the best case for RTX 3090 because of its spacious size.
It’s a mid-tower case made up of mostly steel and aluminum, but there is also a lot of tempered glass on this case, making it aesthetically appealing for RGB builds. The left side is complete tempered glass, while the front has 80% tempered glass while the rest 20% has IO ports. The front tempered glass might be good for RGB lovers, but for performance users, You can install E-ATX motherboards on this case with the bundled mounting bracket, and motherboards like ROG Dominus Extreme can also be installed on it.
There is a single 120mm fan support on the backside, the top and the bottom side have 360mm and 280mm radiator support, and the side has 360mm AIO support. Even the front doesn’t have fan support, but there are enough cooling options, in this case, making it the best in this category. This case is flexible, and you can consider it for any configuration because of the hot-swappable parts, making it easy to install or remove hardware. We also recommend this PC case for RTX 3080 but the pricing might not be for all users.
Considering this case for multiple graphics card configurations, you will love it because of the dual power supply unit support. However, you may need to remove the hard drive cage to make a secondary power supply space. The graphics card clearance is 446mm, meaning that you can easily install any aftermarket RTX 3090 graphics card. A vertical graphics card mount bracket is also sold separately for vertical GPU mount.
The front side has a lot of ports, two USB3 ports on the top IO panel and two on the case feet; there is one USB 3.1 Gen2 Type-C, headphone and microphone jack, and a power button. Most motherboards don’t come with multiple USB3 headers, while some don’t come with a USB 3.1 Gen2 Type-C header. Overall this case is amazing for large-sized GPUs like RTX 3090, but we’ve also recommended it for RTX 3080 because of its features.
Reasons to Buy
- Lots of tempered glass on the sides.
- Side air intake for better airflow.
- Very easy to work on.
- Aesthetically appealing looks.
Reasons Not to Buy
- Must need extra fans to get over the 4000X.
- A bit expensive.
Corsair 5000X was one of my favorite cases for looks, but when you are considering performance, there is a cousin of this case named Corsair 5000D. It might not be as good as the 5000X in terms of looks, but the clean and simple design makes it aesthetically appealing. The steel front panel with lots of air vents makes it excellent for cooling and gives exceptional airflow inside the case.
We gave this case the best airflow case title because it supports up to 10x 120mm fans, while 4x 140mm fans are more than enough for any mid-tower case. One more thing we’ve found better, in this case, is the cable management, as there is 25mm space behind the motherboard tray, which hides all of the necessary cables through a hinged steel door and doesn’t affect the looks of your build.
All from a single 4-pin PWM fan header, a bundled fan controller connects up to six fans and two Corsair AirGuide 120mm fans. The controller allows you to reduce the fan speed when you want quiet operation or increase the fan speed when you want the performance. One fan is installed on the backside, while the other is installed on the front to cool down the graphics card. There should be one 140mm fan on the front side for much better cooling.
You can install one 120mm fan on the rear, one 360mm radiator on top for push/pull, one 360mm on the side, and one 360mm on the front. Two 140mm fans can be installed on the front and topside. Four 2.5' SSDs can be installed on the top side, while two 3.5' HDDs can be installed in the drive cage. The front of this case doesn’t have IO ports while they are on the top with power and reset buttons, USB3 ports, and a headphone/mic jack. Although we’ve bought this case but didn’t make my in-depth review of it but you can check out TechPowerUp Corsair 5000D Review where they’ve covered everything you need to look at while buying a case.
This case comes with a vertical GPU mount bracket and screws bundled in the box for vertical graphics card mount mount mount, but you need to buy the Corsair PCIe x16 3.0 cable separately. This case is quite expensive, but not for a flagship graphics card like RTX 3090. The side panel is heavily tinted, and it will be hard to see inside if there are no RGB fans. Also, the power supply can’t be installed from the rear side.
Fractal Design Meshify 2
Reasons to Buy
- Excellent cooling support
Reasons Not to Buy
- Bulkier design.
Fractal Design cases are well known for their affordable price and lightweight design, and the one we’ve there is a true example of it. The angular mesh on the front and open design layout maintain the airflow inside the case. This case has two variants; one comes with metal sides while the other has tempered glass on the left side. The price difference between them isn’t much, so getting the tempered glass variant will be better.
The front of this case is complete mesh, while the IO ports section is located on the top, which contains the two USB3 ports, one USB3 Type-C, headphone and microphone jack and power/reset buttons. The top supports three 120/140mm fans with a dust filter or 120/240/360mm or 140/280/420mm radiator. The dust filter comes with magnetic strips, making it easy to install or remove for cleaning purposes.
There are seven expansion slots on this case, meaning that it can house any of your ATX motherboards. While for vertical graphics card mount, there are two additional vertical expansion slots. Both sides have tool-less push-to-lock side panels that are easy to remove and install. It has space for 3x 120/140mm fans on the front while 2x Dynamic X2 GP-14 come pre-installed, 2x 120/140mm fans on the bottom and 1x 120/140mm fan on the rear.
There are 3x universal bay drive brackets which can house both 3.5-inches and 2.5-inches drives, and 4x dedicated 2.5-inches drive brackets. The cable routing space behind the motherboard tray on this case is 23mm so that you can hide all of your cables and make your build aesthetically appealing. The power supply unit clearance of this case is 300mm so that you can install any potent PSU for your RTX 3090 graphics card.
The lower compartment of this case is quite difficult to access, and if you are a non-tech guy, you need to check out the manual. In our sample product, the screws on this case are overtightened. There are bundled fans that come with this case, but it lacks the integrated controller, so you may need to go with an aftermarket fans controller. The weight of this case is much heavier than the other casings of this size.
Phanteks Eclipse P500A D-RGB
Reasons to Buy
- Good thermals.
- Great cable management.
- Supports second ITX motherboard.
Reasons Not to Buy
- Too big for simple builds.
- No dust filter on front.
The Phanteks Eclipse P500A is the biggest airflow case from the company as it can host up to two motherboards which is quite interesting for a mid-tower case. You have to buy $20 accessories for this casing, and with them, you will be able to fit an ITX motherboard on the top. There are different variants of this casing, where some are targeted for performance while some are for aesthetics, and we will discuss all of them.
You can get the cheapest variant of this case for under hundred bucks, and it offers two 140mm fans with no RGB lights. While if you prefer aesthetics, you can put $30 more and will get three D-RGB fans, a D-RGB lightning strip, and the power supply unit shroud. If you prefer performance, I would recommend this as the best PC case for RTX 3090 because of its size and features.
There are seven expansion slots on this case, meaning that you can install any ATX motherboard on it. At the same time, there are three vertical expansion slots for vertical graphics card mount. The graphics card clearance is around 435mm, which is more than enough for any aftermarket RTX 3090 graphics card. The maximum power supply length should be 250mm, or under it; otherwise, you will have a clearance issue.
Like the P300A and P400A, this case also comes with front mesh, and the company explains how the mesh wraps the front side and increases airflow. It lacks a dust filter on the front side, so the company’s primary focus is performance. This increases the airflow in the case, but dust will be a problem for you, and you need to be a little more diligent about cleaning the case.
The big size is good for more of the users considering it for RTX 3090, but those making simpler builds will have problems with its size. You can install a 360mm radiator on the front, 140mm fan on the rear side and 3x 120mm fans on the top side or 140mm fans on top. There are 10x 3.5-inches slots for storage drives and 3x 2.5-inches drives, while there are 2x brackets.
Rog Strix Helios GX601
Reasons to Buy
- Graphics Card support bracket included.
- Lots of RGB with Aura Sync.
- Option for vertical graphics card mount.
Reasons Not to Buy
- Slightly heavy in weight.
- Carry handles are impractical.
- Only two slots for 3.5″ drives.
ASUS Rog Strix name is everywhere: graphics card, power supply unit, motherboard, or even the computer case. The Helios GX601 is a premium case in the series designed for enthusiast-class users to showcase their gaming builds online. Ít’s a mid-tower gaming case with three tempered glass panels, an aluminum frame, and RGB lights on the front panel. The solid build quality ensures its long life, and it even comes with one year warranty.
There are eight expansion slots on this case, and it supports motherboards up to the E-ATX form factor, while there are two vertical expansion slots for the vertical graphics card mount. You can install 120mm fans on the top or two 140mm fans while there is space for a single 120mm or 140mm fan on the rear and three 120mm or 140mm fans on the front. The front side supports a 420mm radiator, 360mm on the top side and 140mm on the rear side.
To install the vertical GPU, you need the riser cable, which you need to buy separately, and it supports up to three graphics cards. There are three tempered glass panels on this case which you can install or remove using the buttons on the sides. There are fans and radiator mounts which will make installing and removing the fans easier for you. The front dust filter can be removed from the top, while the bottom filter can be removed from the front side.
Three 140mm fans come pre-installed with this case, while there is a single 140mm fan on this case. Most of the RTX 3090 graphics cards lengths up to 325mm, while this case supports graphics cards up to 450mm in size, meaning any RTX 3090 can be installed on it. A riser cable is required to install a vertical graphics card with cable lengths around 200mm in size. The power supply unit clearance is 220mm, more than enough.
The cable management, in this case, is one of my favorite things as it has 33mm space behind the motherboard tray. The weight of this case is slightly heavier, and its handles are impractical. The two 3.5-inches drive slots on this case are not enough for most users. There are a lot of RGB lights on this case with Aura Sync, and you can produce different RGB effects with them.
Cooler Master MasterBox TD500
Reasons to Buy
- Crystal tempered glass.
- Bundled ARGB fans.
- Spacious interior.
Reasons Not to Buy
- No mounting hardware for all SSD bays.
- Slightly loud under high loads.
The Cooler Master MasterBox TD500 gives all features that an enthusiast needs in his build but lies in the mainstream segment. The side glass panel and lots of RGB make this case a considerable option for those looking for an aesthetically appealing case. This case supports motherboard up to ATX form factor with great cable management. While it can also house E-ATX motherboards, size up to 10.7-inches but some cable management features will get limited.
The polygon mesh on the front offers a 3-dimension contour that offers excellent unobstructed airflow and filters the dust. Three ARGB fans come pre-installed, which are good in performance and aesthetics and worth the money. These fans come with optimized blades and an updated curve that balances static pressure and airflow. They take away a lot of heat from your case without having any noise, even at high speed.
The frame of this case is made up of steel, while there are some plastic parts on the front and another side, a crystal tempered glass on the left side and mesh on the front. The top and front side support 120/140mm fans or radiators, while the rear side supports 120mm fan, and there is no room for fans/radiators on the bottom. With a 410mm graphics card and 165mm CPU cooler clearance, this case can be used for any aftermarket RTX 3090.
In this case, the power supply unit can be mounted on the bottom, and there are vents for air intake with dust filters on them. You can install any ATX sized power supply on this case and not have any clearance problems. At the same time, the top and front also come with air filters, while the rear side lacks it as it’s used for air exhaust, and air/dust doesn’t come inside it.
There are seven expansion slots on this case and no vertical graphics card mount option. There is not enough mounting hardware to take advantage of all four 2.5-inches drive spots. The underside dust filter is not easily accessible or removable. The RGB lights of the fans are controllable with the supplied hardware, but the controller is a bit weird. Overall it’s the best case for RTX 3090 if you are an enthusiast and looking for something affordable.
Reasons to Buy
- Clean aesthetics.
- Good construction arrays.
- Great graphics card cooling support.
- Available in lots of color combinations.
Reasons Not to Buy
- Top radiator cooling can be a weak point.
- Front fans will be more impressive.
- No bundled PCIe extension raiser.
The NZXT H710i is a top-of-the-line gaming case, and it comes with a hefty price tag. However, I think the price is justified due to the features it delivers in return. It’s a big, bold case that screams premium quality from its first impression and every other impression.
The look of the casing is a clean futuristic, sleek look which is quite pleasing to look at; although some might call it bland too, that’s part of its charm. Its sturdy build quality gives a tough time to the competition. It’s no compact box as it’s the top of the line and designed for performance extractors and tweakers who want a PC that hosts heavy-duty water cooling or even air cooling. As per our review, it’s the best case for RTX 3090 to consider in terms of looks and airflow.
It’s not all performance and now looks as if it comes with integrated RGB strips and a controller. You get a smart radiator mounting on top. A button press can open a right-side panel and a tempered glass left side. You even get cable management options behind the motherboard tray to make for a more clean-looking build. The only downside is that the front I/O panel looks a tad empty and could do with an addition of an extra port or two.
Reasons to Buy
- Good airflow inside the case.
- The unique design makes it appealing.
Reasons Not to Buy
- No dust filters.
Cougar has outdone themselves by giving the community a PC case inspired by the Transformers design. The Cougar Conquer case is quite a unique case that is pleasing to look at and features a futuristic design. Cougar has targeted the PC modder community with the case’s aluminum frame can give you multiple modding options due to its unique design that sets it apart from the traditional cases; you won’t need to cut the metal to make space which is like a dream come true for modders. This case looks unique but believes me it can host any RTX 3090 Variant without causing any compatibility issues.
The case itself has a mid-tower case form factor, and it can host a motherboard with a form factor of Mini, micro, and ATX form factors. It has a lot of space for airflow and plenty of openings so that you won’t be facing heat issues in most cases. However, you get space for hooking two 120mm radiators up front and three 120mm radiators on top. The open frame comes with tempered glass side panels that let you display your high-end PC components to everyone who wants to look at the inside. You get three pre-installed COUGAR CFD 120 LED Fans that will help facilitate the airflow, although you can replace them with your radiators.
With the extreme cooling performance and its unique design, the only downside is that the chassis is open from many angles. You will have to make sure that you place it in a dust-free environment; otherwise, you will have to clean it regularly. A unique design makes it one of the best PC case for RTX 3090 in 2022.
PC Case Sizes Explained?
PC case form factors usually come in three categories, ATX, MicroATX, and Mini-ITX. They are named after the size of the motherboard they can host, hence the same name for the case form factor as the casing. You get compact PC cases and the more spacious ones because they need to host bigger motherboards with lots of expansion slots.
PC cases are further categorized by their use case orientation, whether they will be used as a desktop or as a tower. Gaming cases are usually designed in the Tower orientation and they come up with the required support that a standing case would need.
Full Tower Case
To classify a case as a full tower case it must have a height of 22 inches along with a width and depth of 8 inches and 20 inches respectively. These are designed for hosting the larger-sized motherboards that fall under the ATX category and even the Extra large EATX category if needed.
They are designed in a way so that the front side comes with a mesh for optimized delivery flow and also have space for installing fans at either the front or the rear and also at the top if needed. They have ample space inside themselves to host large-sized GPUs, triple fan AIOs, bigger PSUs, and multiple mount drives.
PC enthusiasts prefer this form factor the most as the top-end hardware usually comes with the capability of performing at the extreme level and producing more heat thus needing more surface area to dissipate that heat quickly, hence the big size.
Mid Tower Case
Coming in at 18 inches typically, mid-tower casings usually come in with the same amount of features as their full tower compatriots. They support all sizes of motherboards such as the ATX, micro ATX, and even the Mini ITX motherboards. In some cases, they have enough space between them to host the EATX form factor motherboards too.
They strike a balance between the full tower casings and the Mini tower casings as they have plenty of space for hosting AIOs, drive bays, and large-size GPUs too although some of the Mid tower casings choose to have a trade-off by removing the drive bays and using that space to install cooling fans so that air flows stay optimal all the time. PC enthusiasts are also a sucker for these casings as they have more than enough space to host their high-end hardware and mods so the PC looks as visually appealing as possible.
Mini Tower Case
Mini tower casings are usually classified as having a 15-inch height, they usually support the smaller form factor motherboards such as the Micro ATX and the Mini ITX motherboards.
Since they are designed compactly naturally there is a trade-off between space and the number of features it provides. Nonetheless, that doesn’t mean that you can’t hook in AIO coolers, you just have to go with the smaller ones. These types of casing are also not recommended for the higher-end GPUs as they are very large and will not be able to fit in them.
If you want to build a mid-range PC that doesn’t take up a lot of space then you should consider the Mini ITX casings which come in at 6.7 inches. They have been slowly gaining more popularity in the consumer market as process nodes and other hardware is becoming smaller and smaller with every generation.
While these cases are small that doesn’t mean that they lack in the features department, you can easily hook in most modern hardware except for the higher-end GPUs, although even those can be hooked in some Mini ITX casings that aren’t recommended as you will have issues like throttling and reduced performance.
We’ve tried to make things easy for you and listed out the best case for RTX 3090 that is worth considering these days. In short, if you prefer the looks, I would suggest you get the NZXT H710i, and as per my experience with different casings, I’ve never seen anything more beautiful than these casings but don’t forget they are way too expensive. If you are bored with these rectangular-shaped casings and looking for something unique, you can go with Cougar Conquer, which I like the most because of its design.
Users who prefer performance more than looks should go with the Lian Li O11 Dynamic Xl or Corsair 5000x RGB. These casings are impressive in terms of airflow and thermal performance inside them. I’ve used O11 Dynamic XI in one of my overclocking builds, and the airflow inside the case was pretty good. There are many other options, too, and I’ve even reviewed some different casings but didn’t find them suitable for this build, so in my opinion, you should go with this one, or if you are building an HTPC or compact build, check out our smallest PC cases guide.
