Sun almost certainly won't like this, but I've found that the Sun Blade 100 does just have a normal ATX power supply, with only the ATX connector. Mine failed yesterday, so after looking at the pin outs, I realized that it's just a normal ATX power supply, and plugged one I "borrowed" from a co-workers PC in. Sure enough, it works, and is much quieter (and cheaper) than the crappy 200W power supply that Sun put in there. I'm going to order a modular ATX supply to replace it, as you only need the ATX power lead, and there isn't much room for the extra "standard" ATX cables in that Sun Blade case.
