Heyy everyone.. i'm curious.. i've been looking into putting a 1TB internal hard drive in my iMac.. it's the aluminum 20 inch version 8,1.. not the newest one's that just came out but i believe mid 2008. I could really use some advice on what types of hard drives i could use. i just ordered two 2GB memory sticks to put in so i'll upgrade to 4GB, now i want to upgrade my 250GB hard drive to 1TB. Any help or advice would be greatly appreciated!!!! Thanks!
