Funny you should ask that, I modded mine just yesterday. Not so it would look cool or anything, I just made it to accomodate a 12cm fan. I'll show you pics once I've redone the paint. Basically I did a fan grill template in photoshop, then I printed it, taped it to my case, made each hole indented (so they'd be marked for the drill and so I was able to drill with max precision) then I drilled the holes . I'm looking to do a few more modifications... perhaps add a few neon lights or something.
