There is no way you could run any processor without a cooling device I don't think. Certainly not a SLOT chip, they have fans built onto the chip. You could replace the fan with a peltier device but these chew a wack of power which is bad in the car. But it'd be nice for the home model to have silence (although I'm not sure how quiet Peltiers are). Also, MP3 decoding should take the same ammount of processor regardless of platform but of course the processing overhead of Windoze will crank abit of heat. But just MP3 decoding will push even a low end pentium. A 486 would be pushing it, although Winamp has options to tailor decoding for a 486. Or you could build an ISA decoder card and use a 286 (need own software to pump to card but that's it). Certainly a P100 could do the software decoding and run Windoze. AU$770, that's a bit excessive (both in terms of an MP3 player and in terms of what you're getting). Try this for a similar system: $140 for Celeron 366 (or $170 for a celeron 450) $285 for 13gig ($215 for 8Gb) $50 for 32meg (or $80 for 64) Totals: C366/32Mb/13Gb - $475 + $260 (M/B + display) = $735 (same price but 13Gb with celeron 366 (don't know what you had) and 32 (again don't know what you had)) All these prices are from the TPO (www.tpo.com.au). But that's a good desktop let alone Mp3 decoder. If i were you I'd be heading to a bargain computer store and saving yourself a good few hundred bucks by buying a low level pentium with 32Mb (or maybe only 16Mb) and a seperate sound card and video card. It may not fit under the seat but you'll have a couple of hundred dollars to build a place for it in the boot and upgrade your car stereo.
