GPU upgrades — SFF clearance

Small-form-factor and slim towers often limit GPU length to 180–250 mm and single-slot or low-profile only.

Low-profile: Half-height PCIe cards only — no full-height gaming GPUs without case swap.

SFF towers (Dell/HP/Lenovo): Many accept ~200 mm single-fan cards. Remove drive cages if present for extra length.

PSU: OEM SFF PSUs rarely exceed 300–500 W — do not install a 250 W GPU on a 240 W PSU.

• Low-profile GT 1030 / RX 6400 — Half-height bracket
• Short single-fan RTX 4060 (~170 mm) — Verify total length with power connector
