I've decided to have a go at building my own router/firewall.
I have a nice little Baby AT motherboard with a Pentium 133* which should do the job nicely. It is in a Baby AT case and has an AT PSU.
Firstly, I would like to make it much quieter. So I would probably run the OS off a compact flash card. For a router/firewall, IPCop or SmoothWall would probably do nicely.
Then there's the PSU. Maybe it would be OK to get a modern OCZ ATX PSU like I have in my main PC and use an ATX-AT adapter.
What are the chances of running two motherboards in one case and from one PSU? I'm not too bothered about this at the moment, but it may be a good idea if I decide to set up another machine as a server as well. n.b. I'm not too interested in neatness as most things here are bodged. ATX splitter cables don't seem to be too easy to get here. There seem to be quite a few of them available on websites in America though.
Back to the Pentium, did it ought to run OK without a fan? Currently it only has a tiny fan and a tiny heatsink, but doesn't seem to get very hot.
*Its currently running a fresh install of Windows 95 OSR2, and is working quite well on the internet, despite only having 16MB RAM.
