Hi I got my uncles old Alienware Aurora r3 because I was new and scared to build a pc so I got his old one but now I’ve more experience and wanna upgrade the case since it’s rlly old and bulky but the problem is in the pc I have seen there are 2 motherboards one strip and the main. The main has the main things but the strip has all the things for the fans and stuff so idk if I’m able to swap the case
