Mini tower (Micro-ATX) buyer’s guide
Mini towers are built around Micro-ATX boards. They are typically 320–400 mm tall and 25–40 litres. Most still take full ATX power supplies, 240–360 mm radiators and long GPUs. Newer designs like the Lian Li A3 fit 415 mm cards in 26 L.
Who should buy one
- Budget builders. Micro-ATX boards and cases are cheaper than ATX, with no performance loss.
- Desk-space savers who want something smaller than a mid tower but don't want to deal with SFF compromises.
- Single-GPU gaming rigs. You rarely need more than the four expansion slots mATX gives you.
What to check
- PSU length. This is often the first limit, e.g. 150 mm in the Pop Mini Air. Long PSUs can also reduce GPU clearance.
- GPU thickness as well as length, especially with bottom fans.
- Radiator placement. Top-mounted radiators can hit tall RAM or VRM heatsinks on compact boards.
Desk placement tips
At around 40 cm tall, a mini tower sits comfortably beside a monitor without dominating the desk. It also fits on a shelf or desk-mounted CPU holder.
FAQ
Is Micro-ATX worse than ATX for gaming?
No. You lose a few PCIe slots and sometimes M.2 slots, not performance. Most gaming builds use only one PCIe slot.
Can I put an ATX motherboard in a mini tower?
Generally no. Mini towers are sized for 244 × 244 mm Micro-ATX boards. Mini-ITX boards fit too.
