Motherboard that can support 10+ gpus?

[thanks_bud]

My friends and I are taking on a new project of mining for cryptocurrency like litecoin and possibly bitcoin, and while planning out the rig build, a recurring problem is finding hardware able to support many as 16 gpus. We don't necessarily need a ton of PCie slots, just the capacity to feed and receive information to all of the cards. We've decided this is the best plan because 16 geforce 730's is around $600-$700, which is much cheaper than a couple high performance cards, plus less load on each one for the same amount of work done. We plan to accomplish this with backplanes accompanying the motherboard where each one adds 4-8 PCIe slots per host slot connected to the motherboard. We were also wondering if any cpus around or under $150 are able to handle this load or if we would need a dual cpu board. Custom boards are out of the question price wise and we have most of the other peripherals already figured out.

If you've followed through Computex this year, ASRock had showcased a board that had nothing but PCI-E x1 slots that would be best for cryptocurrency mining rigs. More here.

If he is building from scratch he can get what Lutfij had posted.

If he want to built on what he already has he can use this

but would need a custom case. Also in either case you would need single slot GPU's

Also if you have nothing else connected, and run 16 1x GPU's then you can do it with a single CPU. If you want to run them more at like 4x then yes you would need a dual Xeon board that can give you all those lanes (Or maybe even an 2011/2066 i7/Xeon that has the 28 + PCIe Lanes or wait for AMD Thread ripper which has like 64 PCIelanes
