The AVA platform looks like a great fit for a secure storage server (many cores, AES in hardware, plenty of PCI-E bandwidth).
I couldn't find much info on the actual options for storage however - besides the fact that there's (only) two SATA ports and two M.2 slots, the docs don't mention anything about how much room there is for actual disks. After all, adding a HBA controller to add 6-8 more disks is trivial.
On Twitter, it was mentioned that there is room for three disks: Twitter
Question: what are options, if any, to add more storage to this case? Are there 5.25" slots that can be repurposed by installing a 5.25"-to-3.5" enclosure? Three disks is too little to be useful for storage (3x18TB in RAID5 at most, and that's not really a powerhouse then...).
