Open Frame ATX Mining Rig Case — Thickened Cold-Rolled Steel
A purpose-built open-air chassis for GPU and ASIC mining builds. Constructed from thickened cold-rolled steel plate with a fixed ATX motherboard bracket, this frame provides a rigid, ventilation-first foundation for your rig without the restricted airflow of a conventional tower case. The open-frame design lets heat dissipate naturally from every angle, keeping your GPUs cooler under sustained load.
Frame only. Does not include GPU, CPU, PSU, fans, motherboard, RAM, riser cables, or any other components. Everything pictured with components installed is for illustration purposes only.

Key features
Thickened cold-rolled steel (SPCC) — heavier gauge than typical budget frames, reduces chassis flex under GPU weight
Open-air design — unrestricted airflow around all components eliminates heat buildup from enclosed panels
Fixed ATX motherboard bracket with standard standoff holes — no adapters needed for ATX, Micro-ATX, or Mini-ITX boards
Standard ATX PSU mount — fits any mainstream 150×86mm power supply, no modular-only restriction
No GPU length restrictions — open frame accommodates any GPU length when paired with PCIe riser cables
Powder-coated black finish — corrosion-resistant coating over the full steel structure
Compact 439mm footprint — smaller than many 6-GPU frames, suitable for bench use or shelf stacking
Self-assembly design — flat-packed with all screws included, straightforward bolt-together construction
Optional fan mount positions — add 120mm case fans for active cooling if ambient temperature demands it
Individual retail packaging — packed to protect against transit damage, arrives ready to assemble

Frame only — no GPU, CPU, PSU, fans, motherboard, RAM, PCIe riser cables, or other components are included. Component images are for illustration only. Dimensions are nominal; allow ±5mm manufacturing tolerance. GPU quantity supported depends on the motherboard, riser cables, and PSU used — this is a passive chassis with no inherent GPU slot limit.
