First on the forum and i already have two topics, how cool am i... but really i got a g75 and this is the first notebook i've had since one my old man got me in 2002 which didn't even have wi-fi. how do ssd and opitcal drives work? everytime i try to find out what model ssd fits my machine i get no hits on google, are all ssd the same size? how about optical drives will any of the laptop drives fit or are there different sizes?
