Although this case was extremely great, I did have one major problem with it. The built in PSU failed to power my system. The PSU is only 90W so I guessed it wouldn't be able to do much. I even pulled out the HDD and optical drive to be powered by a second PSU. This however, didn't solve the problem. I ended up running the entire system off of a spare PSU. This problem would be minor, if it wasn't for the fact that the Skeleton doesn't accommodate for a PSU other then the built in one. To me this pretty much ruins the part of having a Mini ITX system, especially if you need a second object sitting on your desk.
