we only have 4. low gaming, high gaming, grandma comp, and a family/htpc.
and the latter 2 are without gpu, in tiny cases.
the low gamer one we sell as a "world of warcraft" model and the higher one is always whatever the flavor of the month game happens to be. we just meet all max settings 1080@60 with minimal hardware possible to do it. right now its an overwatch version, last time it was FO4.
we only have 1 of each ready to ship at any time, with parts to make 1 more. so we order more stuff as they sell.
me and my friend here only make 110 bucks profit on the higher comp. even less on the smaller ones.
it wasnt meant to be a business though, we play with hardware a lot and we couldnt have extra computers sit around aging and losing value so we got rid of em online. it was easy to sell computers that are meant for 1 game, as computer-dumb people generally want a comp for 1 game anyways.
