Pros & Cons

Pros

  • ✓ 18.9-liter dual-chamber mITX chassis with a small footprint for desk or travel
  • ✓ Fits GPUs up to 360mm long despite the compact volume
  • ✓ Supports up to 280mm radiators plus SFX and SFX-L power supplies
  • ✓ PCIe 4.0 riser cable included, so there is nothing extra to buy to mount the GPU
  • ✓ Magnetic side panels and removable PCIe bracket make teardown and GPU swaps faster

Cons

  • ✗ 68mm CPU cooler clearance rules out most tower air coolers
  • ✗ mITX motherboards only; no mATX or ATX support
  • ✗ Needs an SFX or SFX-L PSU; standard ATX power supplies won't fit
  • ✗ Radiators top out at 280mm, so 360mm AIO coolers are out
