** NCIX RECOMMENDS WAITING FOR A REPLACEMENT CABLE ** This thread on our forum outlines a problem with a batch of Fractal Design Define R2 cases that was received by NCIX. http://forums.ncix.com/forums/?mode=showthread&forum=100&threadid=2181595&pagenumber=1&msgcount=21&subpage=1&product_id=51277 If you need to test the front port to find out if your case is affected please use something like a generic mouse as in our testing mice have not been damaged by plugging into the incorrectly wired port, but NCIX does not take responsibility for any hardware damaged by using the front ports. This guide shows how to fix the problem if you don't want to wait.
