I have 2010 Mac Pro. I would like to replace outside enclosure and access door to a new one. So while I'm doing it, I was wondering if I have to take everything apart in the first place. Because if that's the case, then I might as well as clean the fans and unreachable areas. My question is, if you want to replace a case, do you have to take everything apart? (like wires and stuff), or are they all attached to the motherboards so I just have to take the motherboard out (like a PC) and just put that into a new case? Also, is there any Youtube video regarding replacing parts or cleaning Mac Pro? I didn't have any luck finding it. Thanks in advance.
