My pleasure Bumble, reading your post got me started on this juke thing after I finished my arcade setup. I had an email asking some questions and they seemed important so here is the skinny
There is one slot for ram so when I wrote that I put in 256 it was one stick of ram I had. Secondly the hard drive is a standard 3.5" desktop type (western Digital in mine). Lastly mine was as clean as the one in the picture except for what looked like inventory stickers that came right off.
If there are more questions let me know would be happy to take a look again when I get home.
