Lian Li A4-H2OA5 Mini-ITX PC Case, Triple-Slot Mount GPU Silver
The Lian Li A4-H2OA5 Mini-ITX PC Case, Triple-Slot Mount GPU Silver is an 11L small form factor case with a silver aluminum exterior and a matte black SPCC steel interior. It takes Mini-ITX motherboards, graphics cards up to 322mm long across 3 expansion slots via a PCIe 5.0 riser cable, SFX or SFX-L power supplies, and a 240mm radiator on top.
It suits builders who want a full gaming or workstation PC in a compact case that fits on a desk or travels easily. Because space is tight, plan the cooler, power supply and storage together. Our PC builder checks compatibility for you, and we assemble and test it free when the case is part of a PC build.

Compatibility and related parts
Check that your motherboard is Mini-ITX and your graphics card is no longer than 322mm and fits within 3 slots. CPU cooler height is limited to 55mm, so choose a low-profile air cooler or a 240mm radiator whose total thickness with fans stays within 55mm. Browse our CPU coolers, pick an SFX or SFX-L unit from our power supplies, and add 120mm fans from our case fans if needed. Storage is 1x 2.5-inch SSD mount. The PC builder checks all of this for you.
