Hey! Now this is a cool subject!
I think the BMW tower is a bit 'different', but good to see they are playing around with computer tower cases.. .
Alex,
I wonder how Giugaro's computer tower would look like.
I have designed many in my days. One was one under a glass cover and hung on the wall. Supposed to be a art deco thing, (little blinkie lights and things

).
Another is like a fold up large portfolio, ultra thin, large screen, very lite, designed for artists to take their home base computer easily to work or presentations. (big, retractable handle).
My most recent is one I was telling Apple about. Take an iMac 24 inch alum computer (all incased in the monitor), take off the large alum curved base, fit some retractable 'landing gear' into the housing, one at each side, then a built in handle at the top, and a front cover that can be taken off and snapped onto the back, and has the mouse and wireless keyboard in it, and Voila! Another portable desktop...
(I call them computer cross-overs, like a mix between laptops and desktops... )
