Word of advice... rememeber the only point in containing the GPUs in a closed case is to contain the hot air, so you can remove it efficiently via an isolated venting system.
Good luck trying to find the cards mate AMD globally sold our in a week! Nvidia are trying now but they have a BS statement I hear, that they will approach large miners first with the new P104-100/P106-100 GPUs. so unless you plan to buy 1000 + cards in a single order then theres no luck mate :(
Really annoying and hoping Nvidia will not isolate the sales like this.
