I'm almost done with my xbox 360. i've been working on modding it with difference appearance. my first thing that i did was put in a whisper fan blue. it moves more air and is quieter then a regular xbox 360 fan. the next thing that i did was i bought a new ring of light. it now glows blue like my avatar looks like. my friend just cut a hole into the top of the 360 and put plexiglass on it. it look great.  i just painted the 360 faceplate and top of it black. 
 
my next thing i'm going to be doing is cutting a hole into the plexiglass to put a fan on the top of it. the fan is going to be pushing air into the 360. it should be more cooler with the two modded fans. it's going to be also be blue, it will be cool.
