Talking about dumpster diving I remembered that here at the university people just started dumping stuff at the door of our division's building... I found 1 broken LPX socket 5 board, 1 non-working S7 board, 1 ATX case with ATX mounting holes and 1 socket 478 board with a heatsink, but a broken cooler (and no P4). Too bad that recently they removed everything and noone dumps anything here anymore. I just loved waiting untill it was late enough so there wouldn't be a lot of people thinking I'm a weirdo and look around, even if I didn't find anything.
The broken boards are still stored at uni, I brought the case and 478 MoBo home:
The PSU is new... I bought a cheap case to assemble my old i3 for my brother and it came with a crappy 200W PSU (with 25 A in the 5V line). Guess it could be used for an old build. Since the case was already taking the space, I decided to stick it in there. I'm still unsure about what to do with it... I've got no love for P4s, and already have a working Athlon 64 3000+. Maybe I could use it as a base for a "late Win98" build, but I'd rather have a P3 for that. I'm tempted to buy some 478 P4 just to test the board though, and then just forget it in my closet. The case has AT mounting holes though, That might be useful.
