I think that not having my 360 in a dust free area (like in a box type of area, in a case, in a drawer/dresser/entertainment center) is why it has never had any problems…Because it never overheats it is well ventilated. But it gets really dusty down here…So I guess I should try to open it up, since my warranty is up already anyways (this is a launch console that has only ever had one problem, HDD got defected, but no issues with the box itself). Also though, the reason I’ve had no issues could be because it gets freezing down in this basement 
How do you reccomend opening it up? (im worried about breaking it or messing something up when I try opening it, and i have no money right now to replace it so yea..)
