Non-CHN X99/C612 budget motherboard options
It's a bit unusual, but those HP Z4/6/820 boards fit an ATX case. If you're using a V2 board, they should work with V3 CPUs too. For the best value, I'd suggest opting for the budget Chinese models—I've used one before and it performed well.
It seems the board employs unconventional PSU connections. My Z620 likely uses a fairly typical setup, while the 440 probably has a completely different configuration. You might need adapters, but if you're set on a Chinese board, that could be the best option.
I own two CPUs, with the 620 having one on a riser card. I wouldn't suggest opting for a dual socket board since they tend to introduce latency issues. In particular, I don't advise choosing a board where the second socket is on a riser—it can lead to various complications. I'd check HP forums for adapters as they vary by model, but I'm certain they exist for the 620. Uncertain if they fit other models, so proceed with caution.
HP Z440/Z420 boards are available, but Chinese boards from Huanan often offer superior performance.
I don't have personal preferences or aversions. However, if you're referring to a specific topic or context about Chinese boards, feel free to clarify!
