Is this an ok price?

Let me count the ways:

1. Low-end components. Junk motherboard, cheap-ass risers that fail, etc. For mining you want the cheapest hardware possible to maximize ROI. This is not true for password cracking.

2. Running GPUs on x1 slots is fine for mining and brute force, but unless you're working with absurdly slow hashes, it will limit the speed of attacks that employ host candidate generation.

3. Sure, low-end CPU too. Typically you want at least as many CPU cores as GPU devices, but probably more. Also consider that at some point you may need to use CPU for cracking. And surely you'll want to do some wordlist parsing, candidate generation, etc.

4. Limited amount of host memory. For password cracking you need really RAM >= VRAM (or at an absolute bare minimum, VRAM * 0.25). With 2x 1070 Ti + 2x 1080 Ti you should have at least 38GB available host memory. Most cheap-ass motherboards used in mining rigs only support 16-32GB of RAM.

5. Open air chassis suck for cooling (and get really dusty, which also traps in heat.)

@epixoip may I ask you want kind of hashcat attack do you mean by that 2nd point? Do you mean something like I have some external password generator feeding hashcat's stdin? And could you please enlighten me or point me to what to look why are x1 slots slower in this scenario?
