I finished setting up one of the least useful but still pretty cool computer setups I've ever built. I had a leftover desktop PC with no SSD or anything for it, so I set it up to run diskless. It boots Arch Linux using PXE and mounts its entire filesystem from my file server using NFS.
There are no traces of this whole setup physically inside the computer itself, so if you took it out of my house you couldn't see that anything weird like this had been done at all!
