So I finished my pc. Every time I look at it, it feels incomplete. The spot in the back of the case is where a fan would usually go is empty. It kinda bothers the crap out of me. It seems to small for any icue link fans. I was thinking maybe a lcd screen.

Does anyone have any suggestions of what kind of lcd screen or know how big/small of a screen is can put there?
