It is the problem with using a case design from the 80s...it looks cool, but there is a reason why designs have changed that go beyond mere appearance. It is hard to keep a system cool with the amount of heat generated. For example Apple uses an Aluminium build for their computers...yeah it looks streamlined, but really it acts as one giant heat sink for their computer.
It would have been better to build a C64 "inspired" case that made use of modern layout techniques than to try and build a duplicate that would require the voiding of warranties left and right just to make them work properly. I mean I have not owned either a PC or Mac since 2002 that would actually void the warranty if I looked under the hood. Hell both my Dell and Mac Pro would have been voided in the first day given that I usually install new after market components within a few hours of opening the box.
