Having read the comments on this machine while it was being sold by PCMICRO I too recognized the faulty placement of the ram chips. Just follow the table inside the door of the machine. The machine came with a 500gb hard drive not the 320 as...

Will need to buy an adapter


Fast and setup without a lot of extra software
