Micro ATX case for compact builds

Thermals and airflow in daily use

Three front intake fans and one rear exhaust fan create a direct airflow path through the interior. Dust filters on the top and bottom panels help keep components clean. The layout supports additional 120mm or 140mm fans at the top, bottom and front, plus radiators up to 360mm at the front or top and 120mm at the rear.

GPU length clearance decides fit

The interior accommodates graphics cards up to 405mm long, covering current RTX models. CPU coolers up to 165mm tall and power supplies up to 230mm deep are also supported. Front I/O provides USB 2.0, USB 3.0, Type-C and a headset audio jack.

Questions about this item

How do I install the pre-installed 120mm ARGB fans and what step do builders often miss?

The four 120mm ARGB fans come already mounted at the front and rear. Connect each fan's power and ARGB cables to the motherboard headers, then route them behind the PSU shroud. Many builders forget the separate ARGB lead, so lighting stays dark until it is plugged in.

What maintenance will the dust filters need over time?

Magnetic dust filters sit at the top and bottom. Remove them every few months, rinse with water, dry fully, and snap them back. No tools are required and no replacement parts are scheduled.

What thermal limit appears first when the system runs a long, heavy load?

The CPU cooler height is capped at 165 mm, which restricts cooler surface area. Under sustained load this height limit typically becomes the bottleneck before GPU length (405 mm) or radiator space (up to 360 mm) does.
