As rifleman74 said, Blokforge. Their site appears to be down atm. However, they are an amazing company!!! I've ordered from them 3 times, and they were appreciative enough to send me out a coupon a couple of weeks ago. I posted a big thank you promotion for them, and they added some Hashrate to Kano's Pool, as a thank you, although I'm quite sure they're happy they did!!!
