Hey guys, I recently purchased 2 iPod classics off eBay for a very good price. A 3rd & 4th Gen. From the description they are fully operational and do come with original packaging + accessories. Only issue I have with them is that they have been "used" and there is scuff marks on the back plate of both from normal use. I was thinking of self refurbishing these iPods and leaving them in their original packaging. Depending on battery life I would replace the battery and the housing of these iPods. I was wondering if you guys could shed some light if it would be worth even refurbishing and if it would devalue them in the future. Replacing the housing would mean the serial code on the backplate would not match with the packaging and software. Also opinions are welcome. Thanks!
