I suppose you'll be fine then .. but I don't like the idea of paying for something that you don't know the specs for. Do you know how many cores the CPU will have? How much RAM, anything like that? Did he tell you anything other than "it'll come to $617" ?
From what I remember of the conversation, 8 Gigs of RAM, i5 processor(s?), and a 1 TB Black Drive (A fast hard drive.) It was quite some time ago.
