I hate the prospect of selling an old gaming computer on eBay, not because of scammers, but because it’ll get mistreated in delivery. This is clearly a Problem in general, because iBuyPower’s using a fancy packing tech to ensure internal components in its systems don’t get knocked about. From the blurb:
iBUYPOWER Advanced Packaging System utilizes chemical reaction to create an easily removable custom padding solution that molds perfectly to the system. This internal cushion prevents components from shifting or coming loose while in transit, significantly reducing the chance of damage occurring during shipping. The iBUYPOWER Advanced Packaging System is highly recommended for orders with one or more large graphics cards or large CPU cooling solutions.
Better, one presumes, than filling a midi-tower with styrofoam.
