Very nice indeed! If I had the skill, I would make mine look like a Borg cube. I think it would look fantastic, sadly I have little to no creative ability
I think a Borg cube case would actually be easier to make, since it's a cube and you don't really have to mess around too much with trying to fit everything in. Infact, if gives you plenty of room too for cooling and you can even have a basement for your PSU! Get some green LED strips that can fade and flicker, you'd be all set!
It's the actual cutting and design of the case that would be the hard part, you can always get someone else to do all the detail work, then do all the assembly yourself.
