As far as brands go, I would go with Opus. While they are a little more expensive than the M2/M3/M4 ATX power supplies, they are of higher quality. I had an older M2 ATX that would only put out 10.9 - 11.4 volts on the 12v rail (not good!). Since then, I replaced it with an Opus 120w and it's been running strong since 2006. I've also heard good things about the Pico PSU lineup. Pico PSUs are very small and connect directly to your ATX power plug on the motherboard taking up very little double sided tapes space. I would use a Pico PSU if you're extremely cramped for space, like in a glove box build.
