mp3 car computer project... need to find smallest possible AT power supply

[Valhalla1]

have a motherboard pulled from a proprietary system, onboard video and sound and its flat, all connectors in a row.. so it wouldnt fit a standard AT case, but I have the perfect metal enclosure i found in the garbage, its 1" high (will dremel air hole for hs/fan)

it supports up to p133 and i wont have any cards on it since its onboard vid and sb16.. but when I slide the board into the "sleeve" case, there is only room next to it for an AT power supply that is 2.5" wide and 1" tall.

so where could i find such a mini power supply ?

on a related note... what would be the minimum recommeded wattage to run this AT p133 and a 5400 rpm hard drive? and maybe a serial or whatever IR receiver unit. (no kb/mouse/vid)

Will a p133 even be enough to play the mp3s? My 233mmx laptop lags when playing 192kbit mp3's if I tap the mouse.

Sorry, but I have no idea about the power supply.

Good luck and post pictures!

man a 486 100mhz will decode mp3's a p133 is more than enough, it will be running DOS, using Mpxplay http://www.geocities.com/mpxplay/

I just need a way to power it.. it will have a few gb's hard drive that mp3s will be played from there. its more than ample cpu power

surely there used to be rackmount AT cases? slim low profile? surely these had slim small power supplies? any ideas?

what about this, is this a dc-dc power supply?
