Our favorite PC case Asus makes is the TUF Gaming GT501. It's a large mid-tower case and offers excellent value when compared to other options from reputable brands. The chassis itself will support motherboards up to E-ATX, which offers ample customization and build configurations. It's also a stunner, especially in this gray color and the all-metal chassis feels premium to work with. Asus knows a thing or two about cooling a PC and the team behind the GT501 ensured there was plenty of ventilation for airflow in the design. The Asus TUF Gaming GT501 shouldn't be purchased for airflow alone as other full-front mesh panel cases would offer far better performance, but there's ample space for multiple radiators and you won't have any issue feeding case fans with cool air.

The front panel has perforated sides that provide most of the intake and a 360mm radiator can be installed here to take advantage of immediate access. An additional 360mm radiator can be installed up top and there are dust filters everywhere. The 4mm tempered glass side panel is smoked to create a visual splendor when paired up with some internal RGB lighting. Asus didn't cheap out with the included case fans as three 120mm Aura Sync RGB fans are preinstalled on the front panel. An additional 140mm fan is also present on the rear. A further three can be installed up top with the aforementioned radiator mount to aid with keeping everything inside operating within optimal temperature ranges.

In terms of space inside for components, the Asus TUF Gaming GT501 allows for a GPU with a length of up to 420mm and a CPU cooler with a height of 180mm. A standard ATX power supply can be installed beneath the removable shroud. And like some of be quiet!'s more premium chassis, this Asus case allows you to essentially pull it apart when building or performing maintenance. For expansion, we're talking about the usual array of seven PCI slots, though Asus includes an additional two vertical slots for the installation of a GPU with an optional PCIe riser cable (not included). As many as seven 2.5-inch drives or three 2.5-inch and four 3.5-inch drives can be installed. Finally, the front panel I/O lacks USB-C, but we do get two USB 3.1 Gen 1 ports and audio jacks to play with.

We couldn't compile a list of the best Asus PC cases and not include the Asus ROG Strix Helios. Just look at this thing. It's impressive as soon as you unbox it and gaze at the all-aluminum build. There's a full-size RGB panel up front that can be synchronized with the Asus AURA ecosystem and it's not as obnoxious as one would assume. There's not one, not two, not three, but four tempered glass panels that are attached to the aluminum frame resulting in a strong yet gorgeous PC case. If you thought NZXT went too far with the H5 Elite, Asus went all out with glass for the ROG Strix Helios. The internal volume space of the Asus ROG Strix Helios is colossal, allowing up to an E-ATX motherboard and a custom water-cooling loop.

RGB strips can be found inside that also support the AURA software, meaning you should be able to address and synchronize all lighting effects within this chassis, so long as your other components are also compatible. In terms of sizing for the GPU and CPU cooler, Asus allows for a card with a length of up to 450mm, and a CPU cooler can have a maximum height of 190mm. We'd recommend water cooling for such a case, however. You may have noticed that only three tempered glass panels are viewable on the outside and that's because the fourth actually covers the cable management area behind the motherboard. With the side panel attached, this effectively hides the cabling behind two panes of glass, while the area to the rear side is slightly more translucent. Like our top TUF Gaming case pick, Asus includes four fans with the Asus ROG Strix Helios.

Four fans are preinstalled (without RGB lighting) and are all connected to an included fan hub. An additional three fans can be installed. For radiator support, you're looking at up to a 420mm radiator up front, as well as a 360mm radiator on the top panel. Whilst it's not quite as obstructive as other cases on the market, you may find the front panel struggles slightly to draw in cool air through the two available cut-outs.

Seven expansion slots are present, alongside two vertical slots. Four 2.5-inch drive bays are present and a further two 2.5/3.5-inch bays can be deployed accordingly. The front I/O has it all, including a USB-C 3.1 Gen 2 port, four USB-A 3.0 ports, an RGB-lighting control button, and a fan-speed control button.

The Asus TUF Gaming GT301 PC case could be considered the smaller, less expensive sibling to the mighty GT501 case we recommended as our best Asus PC case. It's more compact, meaning you won't be able to install the larger E-ATX motherboards but this does result in the PC taking up less desk space. The design also helps to better differentiate the two. With the Asus TUF Gaming GT301, we're looking at a front metal panel with a perforated honeycomb pattern for airflow. In fact, you could even say this case has a better-designed front panel that prioritizes airflow compared to the GT501. The top panel also makes use of mesh to pull (or push) air through the vents. As with other cases, the side panel is smoked tempered glass.

Like other branded cases, Asus includes three Aura Sync 120mm fans on the front and a single 140mm fan on the rear for the exhaust. A further two 120mm fans can be installed up top. A 360mm radiator can be installed on the front panel and that's all we have for water-cooling support. And as expected, dust filtering covers all intake vents. While it may be slightly more compact than the GT501, there's still plenty of space for even more powerful gaming PC builds inside this chassis. An ATX motherboard can be installed alongside a CPU cooler with a maximum height of up to 160mm. There's also enough space to install a GPU with a maximum length of up to 320mm. The TUF Gaming GT301 has seven expansion slots and space for up to four 2.5-inch and up to 2 3.5-inch drive bays for external storage drives. The front panel IO of the case carries two USB 3.1 Gen 1 ports, a couple of audio ports, an LED control, and a PC reset button.

Asus Prime AP201
ASUS Prime AP201
Best Asus PC case for airflow

Small chassis with great cooling support

The Asus Prime AP201 is an interesting and unique PC case from the brand with mesh panels on all fronts. This not only looks great but doubles up as allowing for solid access to cool air. With support for up to a 360mm radiator, you can build a powerful PC inside this chassis.

Pros
  • Great thermal performance
  • Unique subtle mesh design
Cons
  • Limited motherboard options
  • Four PCI slots

For something unique and less of a gamer look, we'd recommend going with the Prime AP201. This is a more compact chassis that supports Mini ITX and Micro-ATX motherboard form factors, which limits just what can be installed inside the AP201, but does mean it takes up less space. For gaming, it's more than enough for a premium Micro-ATX motherboard, AIO CPU cooler, and either an AMD Ryzen 9 7950X or Intel Core i9-13900K. With the right CPU cooler, it'll be possible to cool anything inside the AP201 from ASUS.

For cooling, we're looking at support of up to 360mm radiators on the top panel. Three 120mm fans can be attached to the radiator or the top panel if an AIO isn't being used. A single 120mm fan can be placed on the rear panel, totaling four 120mm fans, which doesn't sound like enough for more capable PC builds, but they're able to exhaust a lot of heat. Cool air is forced in through the bottom and front panels with the negative air pressure.

The best graphics cards should fit without a problem, thanks to the 338mm of clearance offered by the Asus Prime AP201. Fear not if this is your very first PC build as Asus makes it incredibly easy to get up and running thanks to the tool-free design. Both side panels can be removed without a single screw being removed, offering quick access to all your internal components, and the internal cable management will ensure everything looks neat. Asus sells the Prime AP201 in black or white.

It can prove challenging to locate a solid small form factor (SFF) case to build a PC inside. Most of them are either prebuilt PCs, are vastly over-engineered, or are priced out of budget. It's a relatively small niche within the PC case space but that hasn't prevented Asus from rolling out its own Mini-ITX case in the form of the Asus ROG Z11. The Asus ROG Z11 may be a compact chassis but there's plenty to appreciate about the design, including the patented 11-degree tilt for the motherboard tray and smoked tempered glass side panel. The aforementioned patented design feature aids in providing additional airflow to high-end components that can be installed within the chassis. The additional space created with this layout also allows for more heat dissipation around the CPU and the graphics card.

Up to two 120mm or 140mm fans can be installed on the top panel, as well as two 120mm blowers on the side. Finally, a single 120mm or 140mm fan can be installed on the bottom. If that wasn't enough already, the ROG Z11 supports the installation of a 240mm radiator for an AIO cooling loop. It's certainly a unique Mini-ITX case in that regard. Another advantage the Asus ROG Z11 has over other Mini-ITX cases is the ability to manage cables effectively. And once everything has been put together, the chassis can be positioned horizontally or vertically, depending on preference and location. Unlike game consoles, the dust filters present will help mitigate the amount of dust built up inside. The front panel I/O includes numerous ports for connectivity. You get two USB-A 3.2 Gen 1 ports, two USB-A 2.0 ports, and a single USB-C 3.2 Gen 2 port.

There's also an ARGB control and a reset button on the I/O panel that makes it easier to control the lighting and the system itself. Size-wise, the maximum CPU cooler can be up to 130mm high and the GPU cannot be longer than 320mm. Interestingly, the Asus ROG Z11 allows for the installation of an ATX PSU.

Choosing the best Asus PC case

Those are all our recommendations for the best Asus PC cases. There aren't too many cases available from Asus and we believe these are the only chassis worth considering, depending on the type of build you have in mind. The Asus TUF Gaming GT501 is worth checking if you're looking to build a mid-range to a high-end PC. It has almost everything you'll need to build yourself a powerful gaming PC, but be sure to populate the chassis with enough blowers to make up for the lack of airflow.

Those leaning towards an SFF build can check out the ROG Strix Z11 miniITX PC case, whereas the ROG Strix Helios is more reliable for enthusiast builds. Asus doesn't have many cases available, but we feel as though these recommendations represent the best of what the company offers.
