Case Recommendations for RTX 3090

Lian Li O11 Dynamic EVO

The Lian Li O11 Dynamic EVO is the successor of the all-time popular O11 Dynamic with some additional improvements to its predecessor. It comes in three color variants, modern black, pure white, and harbor gray, and supports motherboards of all sizes, whether it is as large as an E-ATX or as small as a mini-ITX motherboard with dimensions 465x285x459 (LxWxH).

The Lian Li O11 Dynamic EVO’s superior flexibility is what you’re paying for in this case which can allow you to adjust and morph the case to fit your PC parts. It also allows you to reverse the orientation of the chassis to allow you to place the case on the left side of the user while showcasing the system internals. 

Lian Li also offers a wide variety of optional accessories you can buy separately to add more functionality to the case such as an upright GPU kit, front mesh kit, vertical GPU kit, Top I/O, or additional I/O kit. It has many cooling options and supports a variety of radiator sizes. For instance, the top, bottom, and side, all support up to 360mm radiators as well as either two 140mm fans or three 120mm fans throughout all the sides of the case. It can fit three fans on each of the top, bottom, and side and one at the rear making a total of ten fans for the entire case.

It can also support a total of nine 2.5-inch drives or a total of six 3.5-inch drives. That’s a lot of drives. It supports a maximum GPU length of 426mm which is more than enough even for the longest RTX 3090. Additionally, it can support two ATX-sized power supplies in the O11D EVO if the drive cage is removed.

It also features a built-in ARGB strip along the edge of the front glass panel. The I/O ports can also be easily relocated due to their independent I/O module. The I/O is pretty standard and consists of two USB Type-A ports, a USB Type-C port, and an audio jack. However, there is only one magnetic dust filter at the bottom which is disappointing and it tends to fall off as well when handling it.

Overall, it’s a very clean case, especially for water-cooling enthusiasts out there.

Corsair 4000D Airflow

The Corsair 4000D Airflow is one of the top best-selling cases out there and there’s no surprise why due to its extremely sturdy quality and great airflow. Its aesthetic is also sleek and minimalistic which makes it pleasing to the eye. It fits motherboards of up to E-ATX size which makes it a versatile case that fits all motherboard sizes.

Its front I/O is pretty basic, with just a single Type-A port and a single Type-C port, though we would’ve liked to see another Type-A port. The front panel can fit up to three 120mm fans or two 140mm fans. The top can only fit either two 120mm or 140mm fans so you won’t be able to hook a 360mm radiator on the top of the case.

For this case, Corsair chose the theme of being clean and minimalistic and they truly did not disappoint. For the black color variant, it even has a slightly tinted glass which gives it a special aesthetic when your RGB shines through it. Subtle yellow accents can also be seen which gives it a slight contrast and overall gives a premium feel to the case.

Building in this case is rather easy and supports a maximum GPU length of 360mm so it will fit most GPUs even the longest RTX 3090, but you might have to put the radiator on the top instead of the front for it to fit. The case also has a fine mesh filter behind the back panel and is also included for the PSU intake. A magnetic dust filter is also featured on the top of the panel which keeps dust away from the interior of the case. This case comes included with two basic 120mm fans and supports vertical GPU mounting.

For cable management, there are a lot of velcro ties, and zip ties included and case cutouts are correctly placed for easy cable management. There is also a lot of clearance at the rear of the board’s tray for the management of cables. However, one thing to note is that taking off the tempered side glass panel is quite challenging so caution must be taken while doing so.

Overall, a spectacular airflow case that will allow the RTX 3090 to run sufficiently cool.

CORSAIR iCUE 4000X RGB

The Corsair iCUE 4000X case is the RGB version of Corsair’s 4000D and 4000D Airflow variants for an added premium price of $40. It comes with three RGB fans and Corsair’s Lighting Node CORE. The fans included are actually Corsair’s iCUE SP120 RGB PRO fans which have a value of $80 so paying the $40 for this case isn’t too bad. It rocks the same minimalistic design just like the 4000D and 4000D Airflow. 

From the aesthetic point of view, the 4000X rocks a minimalistic clean look and comes in two color variants, black or white. Very much like the 4000D and 4000D Airflow, it supports various motherboard form factors from mini-ITX to E-ATX and has smartly placed cutouts that make cable management a breeze. Ample clearance is also available behind the motherboard tray and the case comes included with many zip ties, and velcros for managing the cables for a clean and tidy look.

The front I/O is pretty lackluster, with just a single Type-A and Type-C port along with the audio jack, reset, and power button. It would’ve been better if there were more USB ports for the front I/O. The case has fine mesh dust filters on the front panel and PSU intake as well as a magnetic dust filter on the top which has subtle yellow accents which looks pretty decent. 

Building in this case is quite simple other than the fact that the tempered glass side panels are rather hard to remove so I’d advise you to exercise precaution while doing so. For this case, you can fit a 360mm radiator at the front of the case or a 240mm radiator at the top of the case. It also supports vertical GPU mounting and supports GPU length of up to 360mm so for an RTX 3090, it may have a snug fit but there is definitely more than enough clearance.

In general, this case is not only skillfully designed but also possesses comprehensive features and looks premium. The additional cost associated with the included RGB fans is quite justified, especially if you prefer to avoid purchasing expensive fan kits separately. Hence, considering both its value and aesthetics, this case is truly worth considering.

HYTE Y60

The Hyte Y60 is one of the most aesthetic enthusiast cases out there with a unique case design that none has ever done before. It has a panoramic glass design and one of the quieter cases out there but is mediocre when it comes to airflow. So this case is for those that value features and aesthetics and performance second. Instead of two glass panels like all standard tempered glass cases, this one gives you three, which gives a wrap-around look to the case. The Hyte Y60 comes in color variants of black, white, and red.

It fits a wide range of motherboard form factors from E-ATX to mini-ITX. It can store two 3.5-inch drives or four 2.5-inch drives which is plenty for a case like this. The Hyte Y60 also comes included with a PCIe 4.0 riser cable which encourages users to do vertical mounting on their GPU. It also comes with three pre-installed fans. The airflow for this case is a bottom-to-top or bottom-to-rear approach which will be beneficial even if you have your GPU mounted vertically. For front panel ports, you get two Type-A USB 3.0 ports, a single Type-C port along with the standard microphone jack and power button.

For cooling options, you can add a 360mm AIO on the top although it may be a little challenging to do so, or a 280mm on the side and a single 120mm fan for the rear. The maximum GPU length clearance is also 375mm. The panels are also meshed for the fan intakes and have a hidden back to hide all the power supply and cabling.

There are some things to consider when building in this case. For example, the rear fan is set too close to the I/O panel so you may have to remove the fan in order to install the motherboard. Functionality and aesthetic-wise, it makes no sacrifices to that department and is a very well-designed case that sets the bar very high for other case manufacturers.

Overall, the Hyte Y60 is an expensive enthusiast case for aesthetic-oriented builds, but it definitely stands out the most compared to other cases and would be a great case to showcase your RTX 3090.
