Titaniums are a bit of a pain to remove the logic board, at least compared to newer Macs. I helped a friend transplant some guts of one Titanium to another and it took a lot of fiddling. The thermal pads on both machines basically turned to glue and it took a lot of flexing and shimming to finally get them to break loose. We're both ACMT's as well, seasoned technicians, and it still wasn't fun.
