Brian, I dont think you have voided your warrantee by trimming the case. You only void it if you run without a fan. You dont need th top of the case to run a fan. I'd zip tie one on at least untill you are confident that the one you have isnt a dud. I know this would be very hard for the ulitmate hater of fanss to do, but to mee it seems prudent considering th situation.
