Hello Zarados,

I've been down that road a couple of months ago and I ended up building a 10 GTX 1060 rig for a little bit more than your budget.

Why GTX 1060 ? Simply because it gives the best ROI, it can produce 23MH/s (with Samsung memory) for 200$ or less. It's very power efficient, I have limited mines to 75W each and the whole rig takes 850W from the wall (all included: motherboard, ssd, gpu, ...)

GPU:
eVGA GTX 1060 (199$)

Motherboard:
Asrock Mining motherboard 13PCIe (141.95$)

SSD:
120Gb SSD (59.99$)
If you do not intend to sync the blockchain, you can take a smaller one.

Memory:
8 Gb memory (59$)
You can take a cheap one here, it's not so important unless you want to run many applications at the same time

CPU:
Low end Celeron cpu (39$)
Unless you want to do something else than mining, you don't need a powerful cpu

PSU:
I decided to take a server PSU to provide power and reliability. I took one from parallel miners:
2400W psu (119$)
2400W is overkill for that price it's unbeatable

PSU:
I took a small and cheap PSU for the motherboard
EVGA 450W PSU (37.89$)
It's a bronze one, you can take a better one if your budget affords it

PCIe risers:
I took some cheap ones from aliexpress:
PCIe risers (30$ for 6, 60$ for 12)
I bought extra cables to connect those risers directly to the server PSU

Total for a 10 GPU Rig:
2447.83$
You can probably go a little bit below by chosing a cheaper motherboard, memory and SSD but I would keep the amount of GPU because that's how you're going to make the money.

Important remarks:
- I did not have to buy a keyboard, mouse or screen, I already had spares
- I'm using Ubuntu, it's free
- you need to have Samsung memory but you can probably use Amazon's return policy (I did it with Amazon France)
- how you put everything together is up to you. I use aluminium bars but I've seen rigs made of wine racks, shoe racks, ...
- you need to include power costs in your ROI calculation. I have solar power.

And the result is the following:

I currently make between 12 and 13$ / day but it will go down as soon as the difficulty rises.

Enjoy!

Interesting, but I have some questions about your mining rig. Why you use 2 PSU while I thought one PSU is enough, Is it because you use 10 GPUs? or you have any other reasons. And how much your electricity cost/month. And how much time to get ROI with this mining rig. Because with this GPUs price ( GTX 1060 3 gb) I also could get it more than 6 with my capital.
