Oh, I like this one. There's no garish colour schemes, no pulsating lights that would look more at home in a Fast & the Furious movie than in some dude's computer. Just a concept, and the smarts to keep the canvas blank so the concept can carry the show.
Its German builder, Jogibaer, makes just about everything white except the cables, giving it that "bleeding on a hospital floor" look that's kinda stylish but also kinda creepy. Especially since he's got an IV bag full of fake blood stashed inside the case.
The system is a few years old, so I won't bore you with the specs.
