Hello guys, my brother and I decided to build a PC that will be used 24/7. We only have a $1000 budget, but we need it to be a powerful workstation that can withstand 24 hour use. I will be using the PC for 24 hour botting, while he will be using it for CAD/CAM softwares that I'm not really familiar with. I gave it a try in pcpartpicker, and I want to know what you guys think?

My brother told me that he needs more "ghz" than cores. The current CPU I chose is only 3.4ghz, and I can't really choose a K version i7 as it will exceed the budget. Should I choose an i3-6320 instead? which is 3.9ghz? But then again, I will be using it for 24 hour botting, so I thought the extra threads would help. Will the PC be crashing/blue screen? We also need it to be reliable during workload.
 
1) I would investigate a higher quality power supply.

2) Motherboard may work fine, but I always spend more on a build like this. Suit yourself. They do have to skimp a bit on parts like capacitors compared to a better motherboard.

3) CPU?
Don't confuse specifications. Look at the TURBO value. Under load you may drop about 200MHz.

The i3-6320 is a poor choice as it only has TWO cores, not four. The i7-6700 is the best CPU for rendering next to the i7-6700K. GAMES are different as higher clock speeds can help (depends on the game), but when it comes to rendering you generally look at total processing power.

i7-6700: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-6700+%40+3.40GHz

i5-6600K: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-6600K+%40+3.50GHz

i3-6320: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i3-6320+%40+3.90GHz

The i5-6700 Turbo is 4.0GHz, and the others are 3.9GHz. The performance is either the same, or better with the i7-6700.

The i7-6700K can run about 10% faster than the i7-6700, but your budget is tight.

4) GTX1070->
Are you gaming?
I would check benchmarks for CAD etc, but I'm not sure how much you gain by going with a GTX1070 vs the GTX1060. It may only be a small gain, however I'm not certain.

You also need to factor in that you could put in an i7-6700K which can gain you 10%.

5) CPU cooler not mentioned. I suggest better than stock (some don't come with coolers anyway) if only to reduce the noise.

6) Windows cost?

So...

I personally would consider the GTX1060 then put the difference towards the i7-6700K as well as improving the quality of motherboard, power supply, adding CPU cooler, 2TB HDD etc.
 
Well, GTX1060 doesn't save much money over that cheaper GTX1070.

I tried to make a build, but I gave up since it was hard to add a CPU cooler, better PSU etc without going over budget. All changes I tried I was not comfortable with.

Your build might be perfect for you, but I'm partially talking about reliability (as well as CPU noise) so those are choices you'd have to make.

*Maybe consider building WITHOUT the graphics card right away and add one later when prices stabilize a bit. Many of the cards are overpriced due to availability.

Thanks for the input, I really appreciate it. If spending a little more (around $100) would improve reliability, then we can probably go for it. I'm not really comfortable about overclocking, so I think we'll stick with the i7-6700. I chose the GTX 1070 for the Cuda, and 8gb vram. I personally don't like the card I chose because it's small. I prefer something like a reference design or dual fan. I would really appreciate it if you can help me choose a better power supply, and motherboard for 24/7 use. If the new motherboard won't have a usb 2.0 header, then I'll probably change the case as well. Consumption in electricity is also a factor for us as the PC will be running 24/7, I don't know if a higher rated PSU would help.
