Holy crap man you need to pick up some cable ties and spare an hour of your time and clean that interior up. The only thing I've done to my case/computer is 5V mod all my case fans, cut a 92MM blow hole in the top of the case, and hot glue my CPU's fan rheostat to a blank 5.25" cover.
Main Rig:
Rheostat, I think it works better than having to reach around the back and mess with the setting.
I don't claim to have the neatest case but this only took and hour.
HTPC:
This was my old case where I cut a window in it. I put it away until I needed a case to house my HTPC. When I pulled it out it was painted bright orange so I half ***ed it and painted it black. Once I build a new HTPC (dual core CPU more RAM/HDDs, etc...) I'm going to buy a nice HTPC case and not have something so ghetto.
