This is pretty cool and all but I think the seller is making a huge mistake selling them in one big blob. It's going to be pretty hard to find anyone willing to bid 100 grand on one item. If he split them up he realistically could sell all of those and make some decent money doing it. With that many items he potentially could make more than 100 grand.
I'm wondering however if some guy robbed some museum and is selling the whole exhibit on Ebay.
Edit: Some sloppy counting puts him at around 200 consoles ALONE not including all of the games. That's $500 for each system even if he wasn't selling a bunch of games too. Not everything is going to go up to $500 but with individual game auctions I think for 100 grand he's missing out on potential revenue. Plus if he sold them seperately he could get the buyer to pay for shipping instead of paying himself.
