SC-4100 Mini-ITX Adapter for Topton

🖥️ Topton X4H to Inter-Tech SC-4100 Mounting Adapter

This custom adapter bracket allows you to perfectly mount a Topton X4H mini PC (N100/N150/N305/N355) inside an Inter-Tech SC-4100 chassis.

The Topton X4H is an incredible, cost-effective board for a DIY NAS or Firewall (featuring 2×10G SFP+, 2×2.5G i226-V, 2×NVMe, DDR5). However, it does not follow the standard mini-ITX mounting hole pattern. This bracket bridges that gap seamlessly!

⚠️ CRITICAL FOR COOLING: A 40×40×10mm northbridge heatsink is absolutely required on the board's chipset to ensure proper cooling inside the enclosed SC-4100 case. I use a generic aluminium heatsink (widely available on AliExpress) with a thermal adhesive pad, and it works perfectly.

🔍 Features & Compatibility

• Tested & Proven: Running 24/7 on my daily driver Intel i3-N305 model under Proxmox VE.
• Versatile: Compatible with all CPU variants of the Topton X4H barebone.
• Clean Setup: Keeps the internal airflow optimized.
