I am after any wattage that can cope with being used all the time, as it is in my home server (Pentium 233) and it is left on almost all the time. The power supply in the case is a huge L-shaped one. I have found sites that sell them (and there were pictures) but they are American!
I noticed that the existing power supply has Apr 1992 on it, which seems to indicate that it is quite old, which could explain why it was full of dust.
Your third link looks the most promising, although it is only 200W, and the one in mine (I think) is 235W. It also doesn't say whether it's a standard size one or a huge one like this.
Thanks for that link. I had been trying to avoid changing the case because the motherboard is Baby AT, and very few cases support these motherboards. Also, this full tower case provides plenty of expansion space for when I install other devices to the server.
I'll try and get the manufacturer of the power supply tomorrow. I think I did a search for it once before, because I thought I would need to get a spare with it being a server, but I found then it ran smoothly so I didn't bother!
