In the entry for the Cooler Master 2011 Case Mod Competition, Peter (a.k.a. L3p D3sk) describes the scratch build as having the following features:
Lots of storage : 10TB+; Overclock potential: 4,5Ghz+; Nice to look at and completely made of aluminium and glass; Watercooled; No cables in sight; Easy to change hardware; And most important, completely silent with cooling beneath my house.
You can marvel at the full specs here.

Whether you love the glowing green and blue lights or think them impractical, you have to give the guy props for designing and building this in eight months.
