txxxx spending time on the innards is fun dude. Adding things such as mods, extra fans, lights just lets a person customize their own case. Besides cleaning out the inside of a case is a really good idea since it allows for much easier access for future upgrades and prevents any electrical mishaps... My cpu fan has a potentiometer on it to change the fan speed and at one point some other wire was tugging on it and this somehow caused the fan to stop. Sufficed to say my cpu got real hot, real quick. Gave me a damn good scare. Now I tape the pot to the side of the case so it's out of the way and won't be touched.
