The plan is to have Debian support for this board. Not sure how much it will be in Italy after delivery and taxes… I think you’ll have to wait for the board to be available for that. We’re expecting it “real soon” (e.g. weeks not months) but ultimately it is not up to us… it is something the board vendor has to decide.
Finally I’ve not seen schematics nor a list of tested SSDs. However it does have a PCI bridge which fans out to onboard ethernet as well as both M.2 (M key style) and mini PCIe connectors. That should permit a fairly wide range of SSD devices to be connected.
