Thanks! Nah obviously I'm not a student BUT, earlier I was saving up money to buy my own place, and during those years I just had a gaming rig, not always filled with high-end parts. I sat on Pentium II/III until ~2006! And I'm sure the first rig-pic I posted here either had a celeron D/RadeonHD2400 or Pentium E5200/RadeonHD4650. Possibly Q8400/RadeonHD4770.
Server, HTPC and a new laptop were bought and put together last year. The years before I just had my main rig (with 1x to 2x GTX 460) and a 15" Sony Vaio laptop. My HTPC was meant to be my server originally but it didn't work out as it makes some faint noise in idle that I could hear at night, and it was disturbing my sleep. So the server-PC behind the dishwasher is sort of an unplanned extra computer, but at least I don't have to see it or think much of it. It's just there, always on.
