Interesting build. With NVMe for OS and fan/heat sink, probably closer to $600. I was also thinking of a similar build with an ASUS Prime MB, eg, 660M-A D4. I find two 3.5” HDDs enough for a mini NAS. NAS storage is cheap, I can populate with maximum capacity. Helios64 was good. But they stopped making the product.
