I blasted it with the water nozzle and then installed one of the older motherboards, etc. I had a couple of new 80cm fans and installed those too. I'm not sure what I will do with the system yet since I don't have a halfway modern OS. I'm planning to buy one of those cheap 2x2.5" SATA drive racks so that I can play around with various hard drives or SSDs without opening the case.
