Start it off at $700. Reserves suck, and if it doesn't meet reserve it's a PITA for those involved in the auction.
There was an SNES I was bidding on a while back. It had a reserve of $35, and bidding started off at $1.00. I put in my max bid ($40) and the bidding went to $2.00. Two more people bid on it, and it finally went up to a whopping $4.00, despite the fact that I put a max of $40 in.)
Include pictures. Clear, well defined pictures. Describe TO A T what the cabinet looks like, what is in it, etc etc. Do a table layout in an HTML program first. Make it look nice. It's a high ticket item, and you want a buyer.
