The new Apple Mac Pro has a shape like a trash can, especially due to the hollow part of it. However, the sleek curved design and the black color gives this device a great look. It also has hard disk bays, beautiful made print board and has no cables like the previous. Check out http://www.apple.com/mac-pro/.
I personally think it looks like a garbage can, but the shape of it doesn't really matter, since its a desktop, and its usually somewhere by your feet. the new shape was supposedly because it helps with cooling the whole thing down, I believe
