Weird development:
the DeskMini H470M-STX barebone with LGA1200 only was announced last August, had some availability since Sept/Oct even before the X300, but now in early December the barebone is sold out almost everywhwere without any indication of restocking. Prices of the remaining few have gone up since November.
It has an upgrade path from Comet Lake to Rocket Lake, so why is it disappearing now after a short run?
There was a sale of the Core i3-10320 for 99 € at the end of November, which I snatched up and wanted to buy a H470M-STX later, but then I saw the dwindling stocks and bought one.
I had disappointing experiences regarding quality with three A300s, the H470 in contrast is a much more mature mainboard. Only the mysteriously low NVMe SSD speeds are unresolved yet.
What I mean by upgrade path to Rocket Lake is visible on the
rear side of the motherboard, a view that Asrock itself does not show: (sorry for the poorly lit pics)
You see the H470 chipset to the right from the backplate, and at the lower left corner a second, yet dormant M.2 NVMe socket for "future generation processors"
The top side is usual STX stuff:
EDIT:
Looking at those pics, I realize these M.2 PCIe sockets are named differently: the M.2 on the upper side is called Ultra M.2, the one on the underside is called Hyper M.2.
Rocket Lake can access PCIe drives directly like Ryzen, so that Hyper M.2 sounds promising
