Remember fellas - the PS3 shown in this tutorial is most likely (almost 100%) the launch backwards compatible model. Meaning, the later FAT models without backwards compatibility WILL LOOK DIFFERENT INSIDE.
Be aware of that as to not wrongly disassemble your precious old PS3.
Great teardown tutorial. Can confirm it saved my butt when I needed to open a 60GB CECHA01 PS3, which I successfully did in addition to (a) replacing the thermal paste, and (b) clean all the dust off.
Only problem with this tutorial is what sonofjay817 mentioned: poor instruction regarding the ribbon cables. THIS IS VERY IMPORTANT: the receptor end for the Blu-Ray ribbon cable needs to have a small black tab pulled open BEFORE removing, and BEFORE inserting the cable. I accidentally got it open by chance, but you might not be so lucky without my warning - and if the ribbon cable is done for, you will need to replace it completely.
