Supermicro SYS-5015A-EHF-D525 1U Server / Firewall Appliance – OPNsense Installed – PCI Riser IncludedUp for sale is a well-kept Supermicro SYS-5015A-EHF-D525 that was pulled from service only because I needed a system with more PCI slots. It did its job well, stayed out of trouble, and never complained about long uptime. This is a compact short-depth 1U Supermicro server built around the X7SPE-HF-D525 motherboard with an embedded Intel Atom D525 1.8 GHz CPU in the SC502L-200B chassis. It is a great fit for OPNsense/pfSense, router, firewall, lab, or lightweight server duty.

Taken offline only because I needed additional PCI expansion.
