I'll take three. I'm on the EK wesite twice a day checking the news. I'm waiting on EK to release the blocks so I can buy the classy's, back plates and blocks all at the same time. The odds are that the blocks will come out and the cards will be out of stock again.
Because of that you should buy one buy one thing if you have chance. Order first backplate and cards, try them, test them and water-blocks will be launched for 1-2 week. Exactly to properly test your card and play few games before installation in loop.
