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 are also interested in small-sized cases known as mini-ITX cases. This article will review 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, many cores, and high TDP. It can consume more than 300 watts at full load, so 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 of the latest-gen 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. Even though full-tower cases are better than mid-tower cases, most 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 can 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 airflow.

If you are building a PC with Nvidia RTX 3090 graphics card, here is the best case you can pick.
Best Case for RTX 3090 Reviews
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 it, making it aesthetically appealing for RGB builds. The left side is completely tempered glass, the front has 80% tempered glass, and 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 only be for some 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 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, a headphone and microphone jack, and a power button. Most motherboards don’t have multiple USB3 headers, while some don’t have 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.
Corsair 5000X was one of my favorite cases for looks, but when considering performance, there is a cousin of this case named Corsair 5000D. The 5000X might be better than the 5000X in terms of looks, but the clean and simple design makes it aesthetically appealing. The steel front panel with many 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 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 expensive, but not for a flagship graphics card like RTX 3090. The side panel is heavily tinted, making it hard to see inside without RGB fans. Also, the power supply can’t be installed from the rear side.
Fractal Design cases are well known for their affordable price and lightweight design; the one we’ve there is a true example. 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 is small, 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.
There are seven expansion slots in this case, meaning that it can house any of your ATX motherboards. While for vertical graphics card mounts, 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.
3x universal bay drive brackets can house both 3.5-inch and 2.5-inch drives and 4x dedicated 2.5-inch drive brackets. The cable routing space behind the motherboard tray on this case is 23mm, so you can hide all your cables and make your build aesthetically appealing. This case’s power supply unit clearance is 300mm, so 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. Bundled fans come with this case but lack the integrated controller so you may need an aftermarket fan controller. The weight of this case is much heavier than the other casings of this size.
The Phanteks Eclipse P500A is the biggest airflow case from the company, as it can host up to two motherboards which are quite interesting for a mid-tower case. You have to buy $20 accessories for this casing; you can fit an ITX motherboard on the top with them. There are different variants of this casing; some are targeted for performance, while others 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 in $30 more and get three D-RGB fans, a D-RGB lightning strip, and the power supply unit shroud. If you prefer performance, I recommend this as the best PC case for RTX 3090 because of its size and features.
There are seven expansion slots in this case, meaning you can install any ATX motherboard on it. At the same time, there are three vertical expansion slots for vertical graphics card mounts. The graphics card clearance is around 435mm, 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. The company’s primary focus is performance, and it lacks a dust filter on the front side. 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 users considering it for RTX 3090, but those making simpler builds will need help with its size. You can install a 360mm radiator on the front, a 140mm fan on the rear side, and 3x 120mm fans on the top or 140mm fans on top. There are 10x 3.5-inches slots for storage drives and 3x 2.5-inches drives, and 2x brackets.
ASUS Rog Strix’s name is everywhere: graphics card, power supply unit, motherboard, or 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, even with a one-year warranty.
In this case, there are eight expansion slots supporting 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, and 140mm on the rear.
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, making installing and removing the fans easier. 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 RTX 3090 graphics cards have 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 of around 200mm. The power supply unit clearance is 220mm, which is more than enough.
In this case, cable management 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 could be more practical. In this case, the two 3.5-inch drive slots must be sufficient 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.
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 viable option for those looking for an aesthetically appealing case. This case supports motherboards up to ATX form factor with great cable management. While it can also house E-ATX motherboards, a size of up to 10.7 inches, some cable management features will be limited.
The polygon mesh on the front offers a 3-dimensional 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 have 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, 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 fans, 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 them as it’s used for air exhaust, and air/dust doesn’t come inside it.
This case has seven expansion slots and no vertical graphics card mount option. More mounting hardware must be needed 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 weird. Overall it’s the best case for RTX 3090 if you are an enthusiast looking for something affordable.
The NZXT H710i is a top-of-the-line gaming case, and it comes with a hefty price tag. However, 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 and every impression.
The casing looks clean, futuristic, and sleek, which is quite pleasing; although some might call it bland too, that’s part of its charm. Its sturdy build quality gives it a tough time to the competition. It’s no compact box as it’s top of the line and designed for performance extractors and tweakers who want a PC that hosts heavy-duty water or air cooling. As per our review, it’s the best case for RTX 3090 to consider regarding looks and airflow.
It’s not all performance, and now it looks like 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 adding an extra port or two.
Cougar has outdone itself by giving the community a PC case inspired by the Transformer’s 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, which 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 like a dream come true for modders. This case looks unique but can host any RTX 3090 Variant without causing 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 openings so that you won’t face 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 to 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 must ensure that you place it in a dust-free environment; otherwise, you must clean it regularly. A unique design makes it one of the best PC cases for RTX 3090 in 2023.
PC Case Sizes Explained?
PC case form factors usually come in three categories, ATX, MicroATX, and Mini-ITX. They are named after the motherboard size they can host, hence the same name for the case form factor as the casing. You get compact PC cases and more spacious ones because they must host bigger motherboards with many expansion slots.
PC cases are further categorized by their use case orientation, whether they will be used as a desktop or a tower. Gaming cases are usually designed in the Tower orientation and come up with the required support that a standing case needs.
Full Tower Case
Classifying a case as a full tower case must have a height of 22 inches and a width and depth of 8 inches and 20 inches, respectively. These are designed to host larger motherboards that fall under the ATX category and even the Extra large EATX category if needed.
They are designed so that the front side has a mesh for optimized delivery flow and has space for installing fans at the front or the rear and 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 have the same 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 balance the full and Mini tower casings as they have plenty of space for hosting AIOs, drive bays, and large-sized GPUs. However, some 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.
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 you can’t hook in AIO coolers; you must go with the smaller ones. These types of casing are also not recommended for the higher-end GPUs as they are very large and cannot fit in them.
Mini-ITX Case
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 are becoming smaller with every generation.
While these cases are small, that doesn’t mean they lack in the features department; you can easily hook in most modern hardware except for the higher-end GPUs. However, even those can be hooked in some Mini ITX casings that aren’t recommended, as you will have issues like throttling and reduced performance.
Conclusion
We’ve tried to make things easy for you and listed the best case for RTX 3090 worth considering. 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 over 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.
