are you doing any whitening to the systems?
also, do the systems (any of them) come with the cover piece that goes on top?
and finally, do you have any idea what kind of price you'd be looking for yet?
Yes, all of the systems have the cover piece. Some are in better shape than others (I have a few with some scratches and marks. Great for keeping the dust away, as well as carrying it around town!
As for the prices I talked about them earlier in the thread so please go back and check. But it will still depend a little on how much shipping will be, the condition of each component, and how complete a set-up you want/need.
As for whitening I haven't done any yet, but I have a few very yellowed original PCE systems and controllers that I want to try it out on one day. I'm a little paranoid about pulling apart the CD-ROM units at this point so I will probably leave them as is.
