Starting my first rig, any feedback is appreciated!

[langy123]

My initial set up will be:

- 2 x Nvidia 1070 GPU's https://www.scan.co.uk/products/gigabyte-nvidia-geforce-gtx-1070-windforce2-oc-v2-8gb-gddr5-graphics-card
- Intel Pentium Dual-Core G4400 3.3 GHz Processor CPU, I did read that the CPU isn't as important, so is this overkill? https://www.scan.co.uk/products/intel-pentium-g4400-s-1151-skylake-dual-core-33ghz-3mb-cache-1000mhz-gpu-33x-ratio-54w-cpu-retail
- 100W Gold certified PSU https://www.scan.co.uk/products/1000w-corsair-rm1000-x-series-80-plus-gold-full-modular-sli-crossfire-single-rail-833a-plus12v-1x135
- PCI risers https://www.amazon.co.uk/gp/product/B073F1QHZ5/ref=ox_sc_act_title_4?smid=ATVCPMRF6NI2O&psc=1

And I have also found various rig frames on Amazon, as well as a power button and a version of Windows 10.

My only issue is finding a Motherboard that will be suited to run what I have found, some I have seen on Amazon have in-built PCI slots, whereas some don't. I am not the best with sourcing Motherboards, but once I have one that fits into the picture, I will be more than on my way.

Please let me know if I should add/remove any components, I will be looking at using the NiceHash program at first.

CPU is overkill.  You could run with a celeron and be fine.

I read 100W PSU and dropped my jaw for a second.  But, the one you linked is 1000W.  The 1070 can draw 150W max.  So, 2x150 + 150W for CPU/motherboard, you are at 450W.  Add 20% for inefficiency and another 50% for load spikes / room to grow and you are around 765W.  So you could get away with a 800W PSU.   If you plan to add more graphics cards later, you could get another PSU.

For motherboards, look for 1 or 2 x16 slots and 2-3 x1 slots.  You can probably find one with a power button built in. 

If you can find Windows 7 cheaper than Windows 10, you can go with that.  Or just run Linux if you are comfortable with that.

For your risers, the only problem may be the length of the cables.  Mine are a tight fit and I had to move one of the graphics cards over to accommodate.

Buy some extra fans to put on the rig and blow air between the cards to help with cooling.

The PSU gives you room to add more cards on the future so it is wise for you to buy a motherboard with 6 x PCIE slots. You can buy Asus H270 prime, I have one and it works out of the box with 4 cards and you need to enable 4G decoding for 5 or more cards. Everything else is fine.

Ok, thanks, I haven't loaded an OS to a motherboard, or started a machine up from scratch, would you say it is easy to do?

Also, do you have any recommendations for a pool to start with, most people are saying NiceHash...

Nice hash is good for beginning and getting paid in bitcoins.
If you are going for good and instant profit, this site gives you some idea https://whattomine.com
If you don't want a hassle and let the rig work, stick with ethereum mining which would be beneficial for both instant trade and long term holding.
