Here's mine: no serious mods, but I did remove most of the honeycomb grill, removed extra cables that I don't need (1394 and eSATA front panels), and put in a fan controller and additional 120mm fans. Also put wire covering on the PSU myself and put grommets between all the fans and the case to reduce vibrational noise.
