I've spent many hours combing these forums and the net for ideas on different builds. I feel confident enough to post what I think will be a good starter rig.

ASRock H81 PRO BTC
Intel Celeron G1840 Processor
Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1600
EVGA 1000 GQ, 80+ GOLD 1000W
SanDisk SSD PLUS 2.5" 120GB SATA III
Electop 2 Pack 2 Pin SW PC Power Cable on/off Push Button
MintCell 6-Pack PCIe 4-Pin MOLEX PCI-E 16x to 1x Powered Riser
EVGA GeForce GTX 1070 SC GAMING
P3 P4400 Kill A Watt Electricity Usage Monitor

The 1070 will run full time, however I am toying around with the idea of buying two of them. When I'm not using my regular PC, I'm going to swap back and forth my 1060 6GB between them. So, lets just assume that I'll be running two 1070's and 18-20hrs a day with the 1060.

At the start, I don't plan on OC'n, but I'm sure I'll reach a point where I'll be interested in doing so. If I can make back what I put into this, I'll add a new GPU here and there for a total of 6 when all is said and done.

I can run Win 7 64 or Win 10. I really haven't seen anyone make a case for one being better than the other, but everyone (using Windows) seems to be Win 10.

Thoughts
No one really metiontions a surge protector. I would assume it would be a good idea to have one. Any suggestions if it's needed?

I'm not sure if it would be a better idea to run two PSU's instead of just one.

What do you think my soon to be peers?
