Mining Rig Frame for 12 GPU Open Air Case - Dual PSU Support

In this review the Mining Rig Frame for 12 GPU is judged as a practical, no-frills open air case for DIY miners who need space and cooling more than aesthetics. It is best for hobbyists and small-scale mining rigs who plan to populate up to 12 graphics cards and use two ATX power supplies. The single biggest reason to buy is the combination of a sturdy stainless steel build and an open design that accelerates airflow, making it easy to keep multiple GPUs cool during extended runs.

Key Features

• 12 GPU slots: Offers room for up to 12 cards, so miners can scale capacity without squeezing components.
• Dual ATX PSU support: The frame accommodates two standard ATX power supplies under 24cm, allowing higher combined wattage for demanding rigs.
• Stainless steel construction: The 1.0mm steel bracket provides a rigid, durable chassis that resists bending when populated with heavy GPUs.
• Open air cooling design: Professional spacing and airflow channels speed convection and make heat dissipation simpler with external fans.
• Organized layout: Plenty of reserved space between cards and mounting points help keep cables tidy and accessible for maintenance.

Who It's For

This frame is ideal for miners building a dedicated rig who want a plain, robust platform: hobbyists, first-time miners upgrading from a small rig, or someone assembling a test bench for multiple GPUs. The support for two PSUs and a single SSD plus HDD slot makes it suitable for compact but powerful multi-card systems.

It is not the best choice for users who need bundled accessories, a full enclosed case, or plug-and-play kits with detailed assembly help. Buyers who expect fans, GPUs, PSUs, or a complete parts set included should look elsewhere and prepare to provide those components themselves.

Pros & Cons

Pros

• Sturdy stainless steel frame gives good physical protection and stability for multiple cards.
• Spacious layout and 80mm slot spacing reduce thermal crowding between GPUs.
• Dual ATX power supply support increases total available power for larger builds.
• Easy to assemble structure for those comfortable with basic hardware and cable routing.

Cons

• Some customers report missing screws and unclear instructions, so expect to verify parts before starting assembly.
• Occasional clearance issues reported between certain card mounting points, so verify card dimensions, especially with aftermarket coolers.

Our Verdict

For DIY miners who prioritize capacity and cooling over packaged convenience, this open air 12 GPU frame delivers strong value: it is durable, roomy, and built to promote airflow while supporting two ATX power supplies. Expect to supply fans, GPUs, PSUs and to manage assembly details yourself, but if you need a solid, expandable skeleton for a multi-card rig this frame is a sensible, cost-effective choice.
