Core i7-5930 requires 2011 socket motherboard, which is about twice the size of 1150 socket, Renderpockets at the moment can fit only the mini-ITX board. i7-5930 also consumes almost twice as much power as the i7-4770, so the cpu stays almost twice as hot, which will require better cpu cooler, and will not fit inside the helmer drawer.. So must make some sacrifice, if you want compact low power consuming 6 nodes renderfarm under your desk, or a very high power 2-3 nodes that are larger than entire helmer cabinet.. The 16GB is max yes, but seems to work quite well, there might be possibility to add micro ATX board which supports 32GB later.
Actually, there will be a possibility to maybe add core i7-5930 cpu later on, but will have to sacrifice 1 extra drawer for ventilation, so 3 rendernodes with i7-5930 instead of 6 with i7-4770!
Back to the drawing board!
