Restoring an Xbox 360 launch team console

I have a 2006 Xenon that had been repaired (it had the GPU replaced, not a reball) which was hot-aired until the GPU shorted out. It's been in semi-often use for a few years now, without issues.

It's about WHO service it and if the parts used are of good quality (new, not recycled parts). Remember, a reball won't magically recondition a failed GPU. It will help only if the real fault was the balls to begin with.
