Decent Prices on PC's at Costco

I posted this over in the Microsoft Tribe forum because these are Windows 8 desktops, but I was talking to my brother and he is looking for a desktop machine to put Linux on. These are pretty good deals for name-brand desktop computers with 32GB RAM, Intel Core i-7, and 4GB Video RAM at $849, $999 and $1299 (without display, with 23-inch display, and 27-inch display respectively).
