Overclockers has an article on building your own tec supply that may be a bit enlightening. I am planning to build a fairly low quality PSU (about 11.5-13v) using much the same components that they did.
In order to get decent power regulation (the 5% tollerances expected of top-of-the-line PC PSUs) requires a great deal more circuitry than what I'm doing. I think the component count of my psu so far is 4: fuse, transformer, bridge rect, and a large cap.
So I guess the answer to your question would be: yes you can bodge one together fairly simply, but you wouldn't want to run your PC off it
As far as UPSs go, the one I have (el cheapo pos) is basicaly a large battery and some circuitry to convert whatever the battery voltage is (I forget offhand) into a stepped AC pulse. So insead of being a true wave forum, the waveforum is kinda boxey and makes CRT monitors squeal
I have thought about making a UPS out of a couple car batterys and one of those "traveling power inverters" that plugs into the 12v jack in your car, but I decided that I already have enough projects on my plate
