ASUS Prime AP201 MicroATX Case: features, specs and who it suits

The ASUS Prime AP201 is a compact computer case for microATX motherboards. It holds a 33-litre volume, which is smaller than a typical mid-tower but still large enough for a full-length graphics card and liquid cooling. It is aimed at people building a desktop PC who want a smaller footprint without giving up airflow.

Mesh panels and airflow

The side panels use what ASUS calls a quasi-filter mesh: more than 57,000 precision-machined holes, each 1.5 mm across. ASUS says this increases airflow and still lets you see the components inside. In general, a mesh panel lets fans draw air straight through the case instead of pulling it through narrow gaps, which usually helps keep temperatures steadier under load. Fine mesh can also reduce the amount of dust that gets in, though you should still expect to clean it now and then.

Cooling support

ASUS lists support for 280 mm and 360 mm radiators and up to six fans. A radiator belongs to an all-in-one (AIO) liquid cooler or a custom loop, and the number in the name is the combined length of its fans: a 360 mm radiator holds three 120 mm fans. Larger radiators typically move more heat away from a hot processor. Check the manual for which mounting positions fit which radiator sizes, since thickness and fan placement can affect clearance.

Fitting big parts into a small case

The listing says the AP201 takes graphics cards up to 338 mm long and ATX power supplies up to 180 mm long. Many current high-end graphics cards fall near or beyond that length, so it is worth measuring the card you have in mind. The case also supports custom liquid cooling and various storage devices. An ATX power supply in a microATX case is a convenience: standard ATX units are easier to find than smaller formats.

Tool-free panels and cable management

A clip mechanism lets the side panels come off without tools, and ASUS says it holds them securely so they don't pop off by accident. Behind the motherboard, the tray is extended and has cutouts placed for routing cables, with a 32 mm gap for tucking them away. In a small case, a deeper rear space usually makes a tidy build easier, especially with a modular power supply.

Size and weight

The listing gives dimensions of about 21.0 x 17.0 x 11.0 inches (roughly 53 x 43 x 28 cm) and a weight of 12.7 lb (about 5.8 kg). Those figures appear to include packaging, so check the case's own measurements in the manual before you clear a space for it.

Who it suits

It suits builders who want a microATX system with strong cooling potential: people planning a 360 mm AIO cooler, a long graphics card, or a desk-friendly tower that still looks open and clean through the mesh.

What to check before you buy

• Motherboard size: the case is for microATX boards, so confirm yours is that size or smaller.
• Graphics card length: compare your card against the 338 mm limit.
• Cooler fit: confirm the radiator size and thickness, and the cooler's height if you use an air cooler.
• Power supply: check that the unit is standard ATX and no longer than 180 mm.
• Storage: confirm how many drives the case holds and in what form.
• Upkeep: plan to clean the mesh panels periodically.

The short version

• A 33-litre microATX case with mesh side panels and tool-free clip-on panels.
• Supports 280 and 360 mm radiators and up to six fans, per ASUS.
• Fits graphics cards up to 338 mm and ATX power supplies up to 180 mm.
• Extended motherboard tray with a 32 mm cable gap.
• Measure your parts against the listed limits before building.
