Here are pictures of the two case mods I have done in the past. Along with the pictures, I also give a small description about the case.

1.

During the day...

...and at night.

This is an In-Win Q500 that I painted semi-gloss black. I cut out the huge "U" from Unreal Tournament into the side and have an 80mm fan up front. This was my first case mod, and have learned a lot since then. Pretty soon, this beast will be demoted to a MP3 or game server. Check out the cool blue neon inside.

My girlfriend's case during day...

...and at night. Nice... :)

This is an In-Win S500 that I modded for my girlfriend, as well as built from scratch. This was my second mod, so I learned some from the first. However, I know more now. I have a 92mm up front and on top, and 2 80mm on the plexi window, as well as another 80mm in back. She gets pretty loud, the case that is. :) There is a cool pink light inside showing off the rounded cabling, which allows for much airflow inside, allowing the 300A to go to 450.

That's it, until my sweet ass Enlight mod is done.
