Oh yeah... I thought I was the only one having massive heat problems... Not to say they weren't unexpected, but no one else mentioned... My WSP:
o Overclocked to 300Mhz
o Running 128megs RAM
o Has a giant Coppermine fan/heatsink on it
o Has a splitter on the power supply running a Maxtor 13.2gig drive and a 32x CD-ROM (sitting on top)
After I had all sorts of difficulties getting it running, I finally got it "just right" and left it on overnight playing MP3s. When I got up in the morning it was too hot to touch and had left a nice mark on the wooden shelf it was sitting on. I am sure the combination of overclocking and running so many devices off the power supply are responsible.
My solution: Drilled a pair of 1" holes in the bottom of the case, just fore of the power supply and mouted a pair of fans ripped from a hard drive bay cooler. Of course I wired those into the power supply, too.. :)
I left it on last night (14 total hours) and it was awesome... No more heat issues. It's reasonably loud, but since the fans are in the bottom they are muffled at least a little. I will try sticking the hard drive inside and see if it stays cool.
If anyone wants pictures, lemme know and I can probably get them...
