When I get the money, I'll look for an Xbox 360 that's unlikely to suffer the problem of having its thermal paste dry up. I may try one of the slim versions, seeing as how they apparently don't suffer from the flaws that the fat units have.
Sad news; my Xbox 360 was made unusable by a mistake in the project. Aside from messing up on the soldering, the x-clamps were needed to prevent overheating. Now my Xbox 360 can not be used. ;_;
On the side of compensations, I did get an original Xbox recently. XD
