Storage expansion (enclosure) options

[Enquiries]

I have a Intel NUC that I'm using as an Unraid server. I have several 2,5" SSD's and several M.2 drives that I would like to add to the NUC. I'm looking for a good way to add several disks, without having to put every disk in it's own enclosure. There are options like the Qnap TR-004, but these are all for 3,5" drives. Any good option available to combine multiple 2,5" drives, or M.2 drives and add to Unrtaid? Thanks in advance!
