This work log describes how I installed an auxiliary fan connector, replaced the crappy orange LED with a blue one, and fixed the stupid short power cord. Now I don't regret buying the cheapo enclosure anymore.
Basically, circumstances forced me to do this mod. The graphics card fan was too close to the side of the case, and it was overheating.
This is definitely my most famous creation. Coincidentally it was also my first work log. It's been featured on Make and Hack-a-Day, because it kicks so much ass.
