PCI backpanel for Mini-ITX (2-slot) — DimasTech S0026RW, aluminium

DimasTech S0026RW is a 2-slot PCI backpanel made from aluminium for Mini-ITX motherboards. It allows installation of two full-height PCI or PCIe cards in compact Mini-ITX enclosures by providing external slot openings and a low-profile metallic mounting surface. The backpanel matches standard PCI slot spacing and is designed for small-form-factor builds, industrial housings, and custom PC projects where external access to expansion cards is required.

Advantages

The aluminium construction offers a lightweight, corrosion-resistant mounting surface with good dimensional stability and heat dissipation compared with painted steel alternatives. The two-slot layout preserves access to adjacent connectors while keeping the overall rear profile slim for compact cases. Precision cutouts and standard spacing ensure compatibility with common full-height PCI and PCIe cards without altering motherboard layout. The metallic finish provides a durable mounting point for fastening hardware and helps maintain EMI shielding continuity at the chassis rear.

Suitable for

• Mini-ITX small-form-factor desktop builds requiring two external expansion slots
• Industrial enclosures and embedded systems with Mini-ITX motherboards
• Custom or compact workstation and media PC projects with limited rear space
• Retrofits where a low-profile aluminium rear bracket is preferred over full‑height rear panels

Key specifications

• Form factor: 2-slot backpanel compatible with Mini-ITX rear layout
• Material: aluminium construction for reduced weight and corrosion resistance
• Profile: low-profile rear mounting surface suitable for compact cases
• Compatibility: standard PCI/PCIe full-height card spacing
• Finish: bare or lightly treated metallic surface for durability and EMI continuity

How to use

Install the backpanel by aligning it with the Mini-ITX motherboard rear I/O area and secure it to the case or chassis using appropriate screws through the provided mounting holes. Slide the full‑height PCI or PCIe card brackets into the open slots from the inside of the chassis until the card ports align with the backpanel openings, then fasten the card to the backpanel to ensure a stable connection. Verify that the card connectors are accessible from the outside and that the mounting does not obstruct adjacent I/O ports or cooling paths.

Recommendations

When fitting in very tight enclosures, check internal clearances for card thickness, nearby cables, and cooling components before final assembly. Use non-magnetic stainless or coated screws to avoid galvanic corrosion where aluminium contacts different metals. Ensure cards are properly seated and secured to maintain reliable signal connections and chassis grounding.
