MotherboardM-ATX and ITX; 4 expansion slots Lian LiMini-ITX only Fractal Design
Graphics cardUp to 415 mm long, 4 slots thick

According to Lian Li, a 25 mm bottom fan limits card thickness to 61 mm (3 slots); a bottom radiator plus fan leaves no room for a graphics card. An anti-sag GPU bracket is included; vertical mounting needs a separately sold kit.

Lian Li		Up to 322 mm long; for cards under 131 mm tall, 72 mm thick in Max GPU mode or 43 mm in Max CPU mode

For cards 131–145 mm tall the thickness limit drops to 62/33 mm. Fractal’s FAQ gives different width figures, so check the manual before buying.
