Seller selling for $500
eBay doesn't keep a very long history anymore, but here's what came up when I searched past listings for "xbox 360 laptop":
Starting bid $350, free shipping, didn't sell:http://www.ebay.com/itm/Xbox-360-Slim-Laptop-Very-Nice-250GB-/180735868081?pt=Video_Games&hash=item2a14b27cb1
Same laptop relisted, sold with one bid at $350:http://www.ebay.com/itm/Xbox-360-Slim-Laptop-Very-Nice-250GB-/180729484784?pt=Video_Games&hash=item2a145115f0
So, $350-1000 depending on quality. People buying these want perfection for the price they pay. It's not that your laptop doesn't work, it's just that the level of finish is not up there with something like Ben Heckendorn's fully CNC'd 360 laptop
. Sorry to break it to you.
You're asking a forum of people who would probably rather make one then pay the large sum you're expecting to hear from someone. I know this because you've asked this question several times, and none of the answers are good enough for you...
There's this too. Unless there is a buyer who comes here with the sole intention of buying a 360 laptop, at least 90% of the Benheck population is young people under 18 (with no money) or college students (also with no money). This is a hacking community, we can help you with problems you have along the way with creating your 360 laptop, but this isn't the best place to sell one.
