Here in EU SSD prices are much higher now but anyway for me the point is not much going "mini" but being accessible and upgradable, in a home setup I do not care much "the NAS" but the homeserver: I do not have a datacenter-as-a-computer where some machines host a gazillion of nvme serving them via nvme or iscsi and so on to some blades allowing easier physical storage administration and greater flexibility, I typically have some desktops used as desktops, a homeserver or two (the second as a spare), so the main point is having a machine to do anything not just backup. A classic desktop rackmounted in a 4-5U, a switch, a patch panel, a UPS, a "router" it's the machine room. Having many small boxes is not much comfy to manage in case of hw issues, having a rack, well accessible, with any component easy to replace is valuable to me. Since the home already consume much more than few W for ventilation and so on the consumption of a modern PC does not change much, it's not an old multi-opteron server.
