Has anyone got a fan (40 x 40 probably) to fit into a modern optical mouse? I made one some 5 years ago in a old school 2 button Microsoft mecahnical mouse, I kind of miss it. I dont really fancy buying loads of opticals until I find one I can mod. Was thinking of a wireless mouse, that way I can have power leads coming out to the computer, the last one I did had the power and data leads braided together and was about as flexable as as a girder.
