I have a slot 1 Pentium II 450Mhz. I took out the noisy fan a year ago and the 7V the power supply fan.

Don't you have ANY fan on either CPU or PSU? What watt is your PSU on? and how is your heatsink built on your CPU?

Another option I was thinking of is using a DOC - Disk On Chip. The MB has a socket for a 32pin flash disk up to 288Mb. But what OS would fit on it ? XP wont (what I am using currently) as it takes up over a gig. I would then not use a HD at all and just run DVD/Divx/mp3 off CD. But then I cant use...

ok.... good cable.... but I meant the other way.... the cable you showed me was a atx -> at converter.... i'm looking for a at -> atx converter...

I have 2 computers: Celeron 300 (Pretty silent fan) ATX Supply 250W (Pretty silent fan)... Pentium 233@266 (Noisy fan) AT Supply 145 - 250W (I have a several to choose from) I'm planning to make one of these to a media box using movix.sf.net That allows a 200-233mhz to play a divx with good result.....

1. Is it possible to convert a AT PSU to a ATX PSU?
2. I have several AT PSU's... Is it possible to run one completly fan-less? or just have a slow5v fan? The PSU i had in mind was a 145w AT... Will thatone run hot?

Thnx...
