Have to say I prefer the simple 'black box' look too. Been looking at custom configured computers, and so many of them have bloody ridiculous cases
Like one computer, perfect for what I want (just slap in a new card), except it's got this fooking idiotic box:

Seriously, what is that giant thing on the bottom? Everything from the waist up is fine, but when you get down to the bottom you've got that washing machine thing on the front.

The only computers I can find with the plain, no frills cases seem to be the most expensive ones...
