Well, working at a computer store has its advantages. Any parts heading off to recycling are in my hands before they leave. Since I started working there my 'project' computers change rapidly. Since I got a KVM switch for $35, I had everything I needed to add something to my collection...
Seanix-branded Generic PC Case
Pentium 4, 1.7GHz with some aftermarket heatsink
Intel D850EMV2 Motherboard
386 Mb of PC-800 RDRAM
I was given the processor for free since we had a bunch laying around anyhow, the motherboard was bound for recycling because RDRAM is a piece of crap that lost brutally to DDR, though I fortunately scrounged up an extra two 64 Mb modules.
The case is from a generic brand of custom-order PC we see a lot. Its a very plain, big case, which is great because you can fit anything you want in there. CPU temp, at full load, will hit maybe 32 degrees

. Without running a fan utility like SpeedFan its easy to tell why. It runs full-out at 4000-odd RPM like a crazy hairdryer.
By the way - I decree that I have received the stupidest injury possible while working on computers. The CPU fan wasn't working so, holding it in my right hand, I was meddling with the wires until it raced up to its crazy speed. Like an idiot, I thought I would put the fan down carelessly while it was running.
I suppose they wanted to get everything they could out of the fan, because I've never seen the blades so razor-sharp.
Slot 1 though, I loved it. Its like the NES cartridge of computer processors. Especially since, at the time, they came with absolutely massive heat sinks in contrast to the bitty things K6-2's and whatnot ran.
I still have a Pentium Overdrive that came with a dinky heat sink affixed to the CPU from the factory, though I doubt heat was a big concern in those "Wow! 100 MHz!" days.
Edit: Thinking of heat, I actually had to undervolt my Pentium III to help bring it down. Since the 1000 MHz processor has such a high thermal design power, the heat sink for the old 600 MHz processor was less-than useful when cranking out instructions. Surprisingly I got it down to 1.5v from 1.7v, which basically means it went from 30 watts to about 22 watts of heat. Nifty stuff you can do behind the scenes with computers.
