Do they actually support the concept of upgrading > HDs? the tech with whom i checked my facts was not the typical ANAL RETENTIVE MAC GUY..he realized people need more HD space..he told me to stick with 5400..people have been successfully putting in 7200..but they do run a high risk of overheating..the pc was simply not designed for that speed of HD..or better put..the extra heat generated by it..he said it may work now..but it will overheat...sooner or later.
