This is the Supermicro-X9DRX-F-B:

Maybe you can already tell by that picture that there is no way of fitting 11 2-slot cards in there. There is a Supermicro server system where you can fit in 8 290x/GTX980 (which is afaik the one Sagitta uses). But that's the max i've ever seen.
And if those things already are too high for you, my advice is to step back down and build a solid 4-way system, which is challenging enough if you've built only standard Gaming-PCs yet.
And sure, if you live in northern Alaska and the server rack is stuffed outside in a wooden shack with constant -20°C, yeah then maybe heat is not a problem (other things are, but whatever). Otherwise it is THE problem.
