Fits comfortably in the palm of your hand.....
Took the wee little fan from a GPU that i got in a box-o-mod parts from Re-Evolution (thanks again Dude).
Well, there ya go. I figured I would go the "novelty" route with this. I have to say thanks to the OP....This little bugger kept me busy most of the night.....alot of sanding and rouging going on here.....
