MotherboardM-ATX and ITX; 4 expansion slots Lian Li—
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 460 mm long; optional VG4-5-V4X/W vertical bracket (PCIe 5.0 riser) or O11DEXL-1X/W upright bracket

Horizontally mounted cards up to 460 mm fit. The upright bracket places the card next to the motherboard; then the card must be at most 358 mm long, 150 mm wide and 80 mm thick (75 mm with a 420 mm radiator top or bottom). Older VG4-4X/W brackets are not compatible.
