I was looking at N class CPU builds and very quickly realized they're not for me. For storage only over LAN, low power prioritized use they're a valid play, but there are some tradeoffs that are not obvious at first glance.

See those NVMEs he stuck in there? They're running at 1/8th their rated link speed. Yeah...12.5%. (PCIe 4.0 x4 vs PCIe 3.0 x1). This board is one of the better ones on pcie layouts [0], but 9 gen3 lanes is thin no matter how you look at it so all those boards have to cut corners somewhere on that

I decided I'm better off with a ebay AM4 build - way better pcie situation, ECC, way more powerful cpu, more sata, cheaper, 6x nvme all with X4 lanes, standard fan compatibility. Main downsides being no quicksync, power consumption and fast ECC UDIMMS are scarce. That was for a proxmox/nas hybrid build though so more emphasis on performance

Hmm good point. But to make sure I understand you completely, this only really matters for compute-heavy workloads, right?
