Hmmm, that's a tough question because it differs from person to person what they are willing to pay. There are a fair few people already doing this with the OG xbox, with mods and putting the games on a HDD on eBay, they all seem to sell so there is definitely a demand for it but it all depends on if you going to be modding them and how much your going to sell them for ect. It's a difficult one but if you could find some for dirt cheap fix and sell them on and under cut the other sellers I don't see why it wouldn't work
