I just picked up a old used 14 core TPM 1.0 Xeon server that came from a school IT closet. The amount of dust inside was scary! I tore down the entire rig and washed everything--luckily it all still worked once I put it back together 😉. These old servers are great ways to get a rig with lots of PCIe lanes so we can add all the NICs, etc. that we want.
