I just won an auction for 25 computers. What should I setup on them? (reddthat.com)

I placed a low bid on an auction for 25 Elitedesk 800 G1s on a government auction and unexpectedly won (ultimately paying less than $20 per computer)

In the long run I plan on selling 15 or so of them to friends and family for cheap, and I'll probably have 4 with Proxmox, 3 for a lab cluster and 1 for the always-on home server and keep a few for spares and random desktops around the house where I could use one.

But while I have all 25 of them what crazy clustering software/configurations should I run? Any fun benchmarks I should know about that I could run for the lolz?

Edit to add:

Specs based on the auction listing and looking computer models:

  • 4th gen i5s (probably i5-4560s or similar)
  • 8GB of DDR3 RAM
  • 256GB SSDs
  • Windows 10 Pro (no mention of licenses, so that remains to be seen)
  • Looks like 3 PCIe Slots (2 1x and 2 16x physically, presumably half-height)

Possible projects I plan on doing:

  • Proxmox cluster
  • Baremetal Kubernetes cluster
  • Harvester HCI cluster (which has the benefit of also being a Rancher cluster)
  • Automated Windows Image creation, deployment and testing
  • Pentesting lab
  • Multi-site enterprise network setup and maintenance
  • Linpack benchmark then compare to previous TOP500 lists

Just two 15A breakers is enough actually. Outlets are supposed to be able to sustain 80% power, so you should be able to pull 1.44kW from a singly puny Nema 5-15.

Well true but I was assuming the circuits had some things drawing a little power. Flipping on a device and tripping a breaker with 12 machines on it wouldn’t be ideal :)

I have done this before in my upstairs home lab. 3 beefy ESXi machines, some nas storage, and a basic 10gbe switch eats up a lot of a single 15amp circuit. And apparently turning on a TV pushes it over the edge. Luckily the UPS saved my but while a reset the breaker and shut some stuff off.
