i got urge other day fiddling imac. 24" 2.4ghz mid 07 model. original aluminum. ive had since new. replaced hard drive once , upgraded second time i've got no problem pulling glass off everything.
last week started doing research on upgrading processor in machine. after finding out in fact socketed cpu found out @ least upgrade "core 2 extreme" higher clock speed. though saw mention of newer penryn chip working. ordered t9300 off of ebay 50 bucks. got buttoned , machine run. system profiler thinks 400mhz processor sucks. ran geek bench on before took old out , got score of 3646 in 64-bit mode. ran penryn process , got score of 3716. makes me think while os x , geebench think running @ 400mhz running @ 2.5ghz speed.
after more research i've realized penryn imacs use e class chips such e8235 2.8ghz chip. im planning pick 1 of these , see if can better/different results
figured i'd share may want this. it's not hard
here geek bench results

after:

just thought i'd add went ahead , ordered intel e8435 chip. it's 3.06ghz chip came in top of line imac in 08. i'll post results when installed.
i've been running machine t9300 2.5 days straight on boinc runs processor @ full load unless i'm doing , temps few degrees lower. i've noticed increased work being completed in boinc , haven't altered usage on machine 1 more indicator chip running @ higher clock speed os x thinks
