Looks like it will be a solid build, you've definitely done your research. I will just make a few suggestions:
1. There's certainly nothing wrong with having more memory, but you may not be able to really take advantage of 32GB in a dedicated cracking rig with only 3 GPUs (depending on what you're cracking.) For 3x 970 I'd recommend 16GB. The money you save doing that can go towards...
2. SSDs. Forget the old spinny disks, grab 2x Crucial CT500MX200SSD1 instead.
3. The Lepa G1600 is a solid unit, there's no doubt about that. But it's a bit dated, and there are some better units available now. You also don't really need a PSU that big, especially with 3x 970s. Your total power draw will only be maybe 600W, and PSUs are most efficient when operating at 50% load. So instead of the old G1600, I'd recommend grabbing an EVGA 220-P2-1200-X1 or Corsair AX1200i instead.
