We had 2-XBox 360's develop the RROD problem at the same time. I have had pretty good results with iFixit's iPod repairs in the past so I decided to give the XBox repairs a try!
Repair went smooth. It does take some patience getting into the case. Took about 3 hours with distractions (kids, T.V., etc.) and the re-assembly was a snap. The first XBox works perfectly! Now I just need to get the parts (heatsinks, screws, etc.) since I already have the tools AND the experience! Thanks iFixit! :-)
Just be patient. Sorry I didn't take pictures but will do so on the next one. :-)
