If youre in search of an E-ATX PC case then youve come to the right place.
Extended-ATX is a marketing term used for motherboards wider than 9.6 inches.
In this post, we will cover both full-tower and mid-tower cases with E-ATX support.
What is the best EATX PC Case?
Thermaltake Level 20 Full Tower
TheLevel 20 Full Toweris a unique looking case thats based on architectural aesthetics.
To achieve this, the unit is divided into three chambers.
The PSU chamber, the motherboard chamber, and the storage (LCS) chamber.
The PSU chamber is the smallest of the three and rests above the mobo chamber.
Here you could store a PSU in either orientation with a 220mm limitation.
Underneath is the mobo chamber.
Whats great is that the deal includes a free riser cable so you might also position your GPU vertically.
The third and final chamber is dedicated to storage.
The chassis is also extremely modular.
This includes three Riing Plus, fourteen RGB fans, as well as two Lumi+ LED Strips.
Another top feature is the TT RGB software that is Alexa-enabled for voice activation.
Modders will appreciate just how well this PC case handles extended ATX boards.
ASUS TUF Gaming GT501
TheTUF Gaming GT501is a mid-tower PC case for up to E-ATX motherboards.
For easy transport, two woven-cotton handles fix to the top.
Although this is a mid-tower case, size-wise its more like a full tower.
It can fit12 x 10.9boards, 180mm coolers, as well as 420mm GPUs.
In the bottom of the case is a PSU shroud that can house a 240mm PSU.
Then, at the back are two 3.2/ 2.5 HDD storage brackets, plus cable space and Velcro ties.
Theres also room for another 360mm top-mounted radiator.
Cooler Master Cosmos C700M
TheCosmos C700Mis a futuristic, full tower chassis that appears straight out of Halo.
It has a highly versatile layout that encourages freedom in building and out-of-the-box customizability.
Other features include a curved, tempered glass side panel and addressable RGB strips.
For that reason, the price is quite high, but so is the build quality.
Aesthetically, you will immediately notice the symmetrical aluminum bars on the top and bottom.
The roof rack on top eases portability when carrying the case, whereas the feet provide balance and stability.
Both bars look fantastic as they reflect ambient light from the RGB strips.
The spacious interior can house up to E-ATX (12 x 10.7) motherboards.
One particularly unique trait is that the Cosmos OS frame supports a conventional, chimney, or inverse layout.
Essentially, this gives you three different options for choosing which orientation you position your motherboard.
As a result, you could showcase your gear in practically any way.
Overall, if youve got the cash, theres plenty of options for E-ATX boards inside this PC case.
Thermaltake Level 20 GT
TheLevel 20 GTis a full tower chassis taken from the TT premium product line.
Aesthetically, the chassis closely resembles others from the level 20 series.
Similarly, the exterior is a combination of rounded aluminum edges and tempered glass panels.
Thanks to the patented PCIe support, graphics cards can rotate in either orientation.
Keep in mind, XL boards will cover the grommets to make organizing cables a challenge.
A removable half-length PSU shroud accommodates the bottom of the main chamber.
Then, to the right of this is room for an HDD Rack that can store four 3.5 HDDs.
Another set of 200mm fans can fit in the roof of the case.
Moreover, theres room for an optional 420mm radiator on the right bracket or a 240mm at the bottom.
All in all, its an extremely big and solid case that offers lots in terms of customization.
Corsair Obsidian Series 1000D
TheObsidian Series 1000Dis a super tower case that takes advantage of a triple-chamber layout.
This consists of the main chamber, a bottom ATX PSU shroud, and a back chamber.
To provide easy access to all compartments, hinged tempered glass panels feature on both sides of the chassis.
We particularly like that they open out from the middle so you wont worry about them closing properly.
Furthermore, as a secondary function, they can store eight SSDs on the insides.
The deal does however come with a free Corsair Commander Pro.
This is compatible with six three or four-pin fans for connecting radiators.
Overall, its an extremely well-made PC case that can concurrently support an extended ATX and Mini-ITX system.
NZXT H710i
TheH710iis one of the larger chassis from NZXTs iconic H series.
Similar features include the classic cable management bar and a full tempered-glass window.
To reach the spacious interior, we particularly like that all of the panels are remove effortlessly.
The front and top panels come off with a pull, and the back panel is a one-button operation.
Conveniently, the glass side panel only uses a single thumbscrew to securely hold it in place.
For your GPU, there are seven standard expansion slots, plus two more for vertical mount.
At the bottom is a full-length PSU shroud that can also fit three 3.5 drives.
Theres lots of room for upgrades, a ton of mounting options and cable management is ideal.
Cables can be hidden behind the management bar or in the preinstalled channels at the back of the case.
An additional 360mm radiator can fit in the top.
For plenty of airflow, vents run along the sides of the top and front panels.
Overall, its a high-quality case thats ideal for first time builders.
Phanteks Eclipse P500A
TheEclipse P500Ais a stylish, mid-tower case that offers excellent airflow.
It features a hinged tempered glass panel on the side and an ultra-fine mesh panel on the front.
The top panel can also support dual-systems when using the optionalITX upgrade kit.
Additionally, a full-length PSU shroud is located at the bottom.
This can house a 195mm PSU with four 3.5mm drive caddies, or a 250mm PSU without.
Elongated slots in the grill provide impressive mounting options for both 120mm and 140mm fans.
For storage, six 3.5 drive caddies are supported at the front of the case.
Moreover, another three 2.5 SSD drives can mount halfway up the back chamber.
Besides storage, the back chamber utilizes several Velcro ties to offer fantastic cable management options.
In short, the P500A is a fantastic case with lots of space and great thermals.
Whatever style of build youre going for, the P8 can accommodate it.
These provide copious amounts of expansion for liquid and air-cooled systems.
Similarly, a vertical PSU bracket and pump mount can fix anywhere along the bottom of the chassis.
The modular design also allows for rotational PCI-e slots in either orientation.
Phanteks Enthoo 719 (Luxe 2)
ThePhanteksEnthoo 719is a high performance, full tower chassis with dual-system support.
Due to its dual-system capabilities, its no surprise that this PC case can support extended ATX motherboards.
The mini-ITX board mounts vertically on the side of a PSU shroud beneath the main chamber.
A second SFX PSU can also occupy this space, but unfortunately, its one or the other.
As a result, a dual-system PSU such as theRevolt Xwould be required to power two systems.
The 719 provides eleven PCI-e slots at the rear with eight being horizontal and three vertical.
For dual vertical GPU support, a free dual-system cover and vertical GPU mount come with the deal.
This allows you to showcase both systems spectacularly through the side of the case.
For features, we particularly like the integrated fan hub that is tucked away in the top back chamber.
This can connect five 4-pin PWM outputs and three 3-pin DC outputs.
Overall, its a fantastic case that offers tons of space and great cable management.
At the bottom of the main chamber, a protective PSU shroud takes up two-thirds of the width.
Besides using the side bracket for drives, it can also store four 120mm fans or a 480mm radiator.
Due to having a modular design, most of the internals are held in by screws.
This makes it easy to remove things like the PSU shroud, drive brackets, and HD cages.
Overall, the Crystal XL Pro would make a great choice for anybody wanting to build something special.
Fractal Design Define 7 XL
TheDefine 7 XLcombines flexibility with functionality while flaunting a minimalistic style.
Designed to be modular, the chassis opens up fully to expose the interior of the case.
It also includes a second top panel that you could swap out for either silence or performance.
Whats great about this case is that its very user friendly.
The majority of the panels use tool-less latches that quick release with a bit of a pull.
Once removed, there are effectively two main builds you could go for; open or closed.
The open layout is one large spacious interior.
Conversely, the closed layout brings a third of the back-panel forward to block off view from the side.
This allows you to hide 11 drive trays behind out of sight.
480mm radiators can fit in the front or top and theres room for a 240mm in the bottom too.
Also found in the bottom of the case is a ventilated PSU shroud with a two-part removable cover.
Then, in the back chamber, there are multiple grommets and straps to fasten your cables.
Lian Li PC-O11 Dynamic XL
The LianO11 Dynamic XLis a modern, full tower chassis with a dual-chamber layout.
Much like the original, theres a reason why so many people openly praise this case.
In addition to 446mm GPUs, and up to three 360mm radiators without any interference.
We hope you found an E-ATX PC case on this list!
