Some valid points there mate. I know um, 10 people with a 360. All of them except one has had the RROD failure, so that's a 90% failure rate over here. One guy is on his 3rd (and he's not a heavy gamer); another guy is on his 6th.
List of flaws, wow, where do I begin?
GPU heatsink that is Waaaaaay too small to cope
Fans that run too slowly; not enough cool air being pulled through the heatsinks
Poor fan shroud design - air leaks in around the sides instead of over the heatsinks
Poor quality, thin motherboard that warps easily
Poor quality, brittle lead-free solder
X-clamps pushing up and causing point pressure underneath the GPU and CPU chips
Poor quality and excessive thermal paste being used
Two centre case standoffs higher than the edge of the case (forced warping of the mobo), although I've noticed they've fixed this with the newer 360's and these are now level with the edge of the case where the mobo screws down.
Microsoft cut every corner they could, anywhere they could, to push the 360 through the door as cheaply as possible, and before the PS3 came to market. They are now paying the price, as it's cost them over a billion dollars in repairs. If it were any other company, they would have gone bust or given up on the 360. Microsoft's *cough* attempts at fixing this broken abortion of a console so far include a small extension to the GPU heatsink and epoxying the GPU and CPU chips into place, LMAO - these still break...
Reflowing the cracked solder underneath the GPU chip followed by the HYBRID X-clamp repair, then pushing 12 volts through both fans and modding the shroud by sealing it up around the edges and covering the GPU heatsink, then adding mini heatsinks to the exposed RAM chips, the HANA chaip and the Southbridge chip, is a pretty robust and long lasting repair.
Other than this, the 360 needs a complete and fundamental redesign to prevent the RROD/e74 and related errors.
