I just retired two little hypervisors.

Looking for $350 for each MB/CPU/MEM/NIC combo or $600 for both!

============

H8SGL-F Supermicro single CPU motherboard /w IPMI /w dual 1GB NIC /w 6 
SATA ports

AMD Opteron 16core CPU /w cooler (6386 SE @ 2.8ghz)

128GB 1333MHZ ECC RAM (8x16)

dual 10GB intel NIC card (Ethernet, not fiber)

============

They have been running Cent7, Rocky 8, RHEL7 and RHEL8 for years. Solid 
workhorses.

Ping me if you need pictures - happy to send.
