Off-board/External ATX Power Supplies?

atomicretro asks: "Basically I'm on a quest for a silent PC, so I am looking to take my ATX power supply unit, external. I was simply wondering if anyone else had tried this with any success, or any commercial companies sold them. Silence is required as this PC is being used in my dorm room, and it's hard to sleep next to a whining PC. I've got the sound levels pretty much down to a minimum by adding various silent PC parts, but a separate power supply would be pretty cool. Any help or ideas accepted!" There was a similar question that was posted about two years ago, and it would be interesting to note if anyone in the market was listening.
