I have a Shuttle SN21G5 that comes stock with this psu: Shuttle PC40 SilentX XPC 250W Power Supply, bulk-pack. SKU: PC 40 My question is, would I be able to replace this psu with either of these? SPI3501UH-B204 Sparkle SPI3501UH-B204 350W 80Plus 1U Switching Power Supply - Server Power Supply - SuperBiiz.com or Sparkle SPI4001UG-B204 1U 80 Plus Power Supply 400W I know the dimensions are a little different but that's nothing a little dremel work won't fix =). Thanks.
