If you love to build your own computer system and pimp them out you should check out the new show called Mod Men. They take some stock computer parts and mash them into some cool creations. Custom paint, milling machines and more is what they use to take ordinary computer systems over the top.
My favorite part of the first 2 episodes is at 9:04 of episode 2 where they show you how to make a cheap computer mouse look like it has a carbon fiber cover. All they use is some paint and a cheap non-slip mat. The results are impressive.
