You still need a case, PSU, and of course OS figured in the cost. Whenever I see Genuine Windows 7 on ebay that comes with recovery discs, I think it isnt genuine. And in most cases that is indeed the case on ebay. Does anything actually come with recovery discs anymore? So what is your final cost with everything you havent listed including the OS. Im kinda doubting youll be able to sell it for much of a profit. Altho I could be wrong.
Well keep in mind with ebay, you pay to list it. You pay a fee when it sells and PayPal takes a cut when the money is xferred. Sell a lot of custom HTPCs I build on ebay and if you dont price it correctly youll lose your ass.
