I agree if the seller is wanting to accept paypal the fee should be in him. I dont accept paypal any longer since they locked my account and took all the money in it after I was the victum of a scamm. The ruled that since I sent to a gift address and not the confirmed address I was in the wrong. Funny how they offer that service and screw you for using it if things go wrong!!
That A4000 is real neat. I've seen a few, but never tried o get one. I bought an A3000+ complete a couple years ago that has the same type of material that motherboard is made from. I would say its very real.
