ASUS isn't known much for making PC cases, but they have and are quite good. This pattern continues with the case they sent us today, the Prime AP201 mATX. So why don't we look at this mATX chassis from ASUS and see how it ticks?


Packaging



The packaging on the Prime AP201 is pretty standard, with the standard brown cardboard box with a design of the box on the outside. Moving to the side of the box shows the specifications.

Once opened up, the Prime AP201 is protected by another industry staple, two form-fitted soft layered foam pieces to take the abuse of shipping. With the foam end pieces removed, all that's left is to remove the plastic that covers the Prime AP 201 from anything else that might nick or scratch the outside.
Outside the ASUS Prime AP201

The Prime AP201 in white is pretty good looking, if I say so myself. Mesh in the front, mesh on the side - mesh mesh mesh. All good, right? Well, we will talk more about that when we get to the testing later in the review.

The front I/O of the Prime AP201 is pretty well featured for an mATX case. Starting off strong, a 10Gbps USB 3.2 Type-C port, separate 3.5 headphone and microphone ports, a square power button with an activity light ring around it, and two USB 3.0 Type-A ports round out the front I/O nicely.

The rear of the Prime AP201 shows four PCIe slots with a lot of ventilation via square cutouts. Also, the power input has been relocated to the upper left corner to allow a front-mounted PSU. A white 120mm fan is mounted in the rear position to aid in exhausting hot case air.
Inside the ASUS Prime AP201

Once the side mesh panel is removed, an open chamber is revealed with the PSU mount on the front wall.

A closer view of the front-mounted PSU mount. This mount can be mounted to three heights for easier clearance for GPU mounting length. Note if the PSU is mounted in the top mounted slots, this might restrict mounting a 360mm radiator or AIO depending on fan and radiator thickness.

The front cover hides most of the cabling from the PSU and adds some structural integrity. Four silver screws hold this panel in place.

The bottom of the Prime AP201 can accommodate three 120mm fans and a 360mm radiator.

Taking the rear mesh side panel off reveals behind the motherboard tray, which, mind you, has some decent cable management. A large cutout in the motherboard tray allows the installation of CPU water blocks, CPU air coolers, and CPU AIO water coolers.

Also supported is a single 2.5" SSD/HDD mount on the rear of the motherboard tray.

The front of the Prime AP201, with the front mesh panel removed, possibly shows mounting for a GPU support bracket, but this is unclear. However, no support for a front-mounted fan is possible.

Sliding the top panel off to expose the bare top, which again supports three 120mm fans or a 360mm radiator. Two 140mm fans can also be mounted along with a 280mm radiator.

ASUS includes a user manual and silver screws with rubber dampeners for HDDs.

Here is the test system mounted in the Prime AP201. Again the cable management was pretty good, with very few cables showing or getting in the way of installing the rear mesh side panel. The cable management raceway also has three white velcro cable tie-off points. However, the top one is a bit too high to use with any cable thicker than a fan cable.

The test system installed in the ASUS Prime AP201, which has an Intel Core i5 12600K on an ASUS B760M motherboard, an NVIDIA RTX 3090 FE, which is powered by the ROG Loki SFX-L 850w ATX 3.0 PSU.

Final Thoughts

Running around a little over an hour on the system stability test via Aida64 Engineer, let the Core i5 12600K from Intel idle around 30C with a total load temp running up to 92C. While this may seem a bit toasty for some, this is completely within the spec of the Core i5 12600K.
I suggest using a 280mm AIO water cooler instead of the tower air cool I used, which should bring temperatures down to a more reasonable level. The NVIDIA RTX 3090 FE sat at 36C idle with a 68C load temp, which is very impressive for not really having any front air intake to provide cool fresh air.
My final thoughts on the ASUS Prime AP201 are pretty good. Having an MSRP of $79.99, one really cannot complain too much about anything. The build quality is good, and every little aspect has been thought through for a build to go smoothly. That said, I would have really liked the option to mount another 120mm fan in the front for fresh air intake.
Overall the ASUS Prime AP201 is a larger SFF case, measured in at 33 liters. The Prime AP201 can fit its fair share of larger hardware, not to mention all sorts of liquid cooling options needed to cool higher-end hardware efficiently. So if it looks like the mATX form factor might be making a comeback, and the ASUS Prime AP201 might just be the mATX case you are looking for in your next build.
