I'm selling a custom built GTX 580 build on ebay, and I'm concerned about shipping. Has anyone ever shipped a PC with an installed GPU? Or more specifically, one as large or heavy as a GTX 580? Is it safe to ship already installed, or would it be best to remove it and ship it seperately and eat the extra shipping fee? I understand that I can get insurance, but does it only offer protection if there is visible damage on the package? Even if it arrives at the customers door intact, should they decide to return it and have it become damaged in the return shipping, then would I be at a loss? I will be shipping the PC in the box that the chassis came in. Any help would be much appreciated!
