What motherboard can you buy for under 50 with 6 PCIeX16 (power) slots? The cheap "bitcoin" motherboard that go for about 50-75$(old intel express chipset) won't work in this case, not sure about the 1070 but the 980 (non-ti) and the Titan X do not want to work with any PCIe slot that isn't a true PCIeX16 power slot. The PCIe x1-4 to x6 riser converter boards do not work, even the "good" ones with a SATA power connector and an actual power PCB for some reason, my guess is that there is some actual sensing going on in the card itself.
Unless you buy something like this http://www.amazon.com/ASRock-Motherboard-H81-PRO-BTC/dp/B00H... which which is i think the only non-server motherboard which is commonly available you aren't getting more than 4-4 PCIe slots, and even to get 4 (PCIe16) you need to spend about 200$ on a motherboard these days and the H81 chipset mobo's don't want to work with modern nVIDIA cards (or the other way around) with all but the main PCIe16 slot.
Pretty much to get more than 2 PCIx16 slots these days you have to buy a good gaming Z170/Z97/X99 motherboard, that ain't cheap, nor are the CPU's that go into them. While the AMD CPU's might be a bit cheaper again the motherboards won't be.
P.S. my personal password cracking setup at home is 4 5970's you could get them for about 100$ even a couple of years ago (today they are much cheaper 2 for 130 or b/o: http://goo.gl/yplISa) and for most hashes they go 40-50% of the perofmrnace of a Titan X (I do have 2 Titan X's in my personal gaming rig which i can use in a pinch). I got them setup on an ASROCK motherboard (h61 iirc) that was designed for bitcoin mining so it comes with 8 PCIE slots and powered converter ribbons connect the cards do it all of this sits in a al cheapo rackmount case of a 20 year old compaq server.
But if you are looking for more scalable compute instance AWS CUDA instances are probably a better solution and I've been using them more and more lately.
