This is a platform that I built around a miner's card (Gigabyte Aorus RX580 8G) that I got prior to planning this build.
I wanted a computer that I can use for Kaggle, as well as for testing out different architectures for deep learning. Guided by the principles described in this article (http://timdettmers.com/2018/12/16/deep-learning-hardware-guide/), I set out to create a build capable of meeting my needs without breaking my bank.
I wanted to create my first Ryzen system, so this actually turned out to be an all AMD build. The icing on top of the cake would be the orange individually sleeved Phanteks cables, allowing me to stick to the Gigabyte Aorus color scheme.
The only hurdle I encountered was the fact that my NZXT H200 case came in with two fans, while my motherboard only allowed for one CPU Fan and one system fan header. Thinking about whether I should pursue a cable splitter, or just wait for the NZXT X52 Kraken AIO that I'm considering as an upgrade path (that way my CPU cooler wouldn't need the CPU Fan header).
03/26/19-EDIT: So I tested out the advice to use cable combs as soon as I got home. The combs came along with the Phanteks cable extension pack and they worked like a charm.
In addition, I added some photos of the back of the case to show its cable management. It might be a bit sloppy, but considering it's my first build I thought I could cut myself some slack. Also, it may have something to do with the luxury of not (yet) having the 240mm radiator and fans--I have plenty of room to hide my cables under the power supply shroud.
