Let me describe my current situation.
I want to make a basic server to do two tasks; host Transport Tycoon and FTP servers. None of them really requires that much computing power and my connection is fast enough, I would assign those tasks to my current PC, but it was built to do some serious gaming so it consumes more power on idle than I want my server to consume while servering. Actualy right now, while I am just writing this with chrome open it's eating up 120W.
I searched my entire house and nearby places for components that I could use to make that server for basicaly free, but I ended up with some 2000's graphics cards, 1GB of RAM combined and no PSU. However, local school was getting rid of it's servers from which I managed to scavange six Xeon CPUs, four 32-bit 5150s and two unnamed (Intel Xeon '04) ones, I suspect they are 64-bit, single-core 3.40GHz, socket 604.
So as you can see I have nothing right now, except a bit of money that I would like to invest in that server. Any advice to get the cheapest-to-buy and cheapest-to-run server would be very appreciated. If you have some ideas for what I can do with those Xeons, that would also help (maybe).
I am not afraid to buy old used stuff from ebay, I actualy went to the local scrap materials place and searched some computers there while it was raining on me (and those computers), so yeah...
