2 out of the 4 feet on the bottom of my Computer broke off accidentally, so i designed this replacement for them. My Case is the AeroCool VS-3, but i think it also should work for different ones. They are a tiny little bit smaller than the original, but that doesn't made any problems with me (even if you only replace one, it will propably still stand stable)
Check the Instructions for further Informations.
If anything is unclear just write a comment wich i will answer as soon as i see it.
