I saw this awesome looking Wii that someone modded to have a Super Mario Galaxy theme. This isn't my auction nor am I affiliated it with any way, but I'm just posting its eBay link so that you can see the pictures:

That guy did such a good job. I love how it lights up. If I tried that with my consoles it would look like a glue gun explosion and would probably end up burning a hole through it.
