Ok, you make a really good point. I’m starting out, you know a thing or two. How would you start out, knowing what you know now?

3 x anything is not an option. I’m 1 and done. 👍🏻

I have a soft spot for AMD and I’m considering the R9 7900 or (lesser known) R9 PRO 7945 (it has AVX-512 support, which I understand is beneficial in the ML world) for the CPU, but heard AMD GPU support was lack in some workloads and I really don’t need that learning curve.

I can only afford and justify the space of one CPU so 3 x something is out of the question.

I looked at the P100, but read the 4060 was the better choice. I’m at a little bit of a loss. A 3u chassis looks like the way to go, and I have the option to water cool either the CPU or GPU.

Home brewing is exactly the way I’m going. A 3u is on the table, I’m looking at the sliger chassis’s at the moment, but cooling a space is a big consideration.

To be honestly I had only considered 1 GPU, I live in the UK and electricity prices are high (and houses are small), so multiple CPUs just don’t seem appropriate.
