Thanx guys... I am trying to piece together this machine I bought. THe logic board number is giving me problems since I cant find out much about the machine specs online. I bought this machine which is brand new but is only power supply and logic board, that's it! I have the hard drives and optical drives etc. But I need the carriers for the drives plus a processor. I cant find out which one to get cause the information is hard to find. Any suggestions? The logic board number is:820-1453-A
