Been tinkering with this for a few months now, centered around experimenting with making my own reservoirs. Sculpted in clay and then cast in two halves with epoxy resin. Complete pain in the arse to tap threads for the fittings! Had a bunch of clay so I decided to sculpt a load of cable/pipe management bits out of them, I thought it gave it a pretty interesting look. I also left the cases outside for most of winter to let them corrode a little. Hardware is pretty basic, mostly salvaged: Intel i5 2500 3.3GHz 8Gb DDR3 256Gb SSD Running this as a socket server for hosting multiplayer games I'm building so didn't bother with a GPU as it's usually running without any GUI anyway!
