What is the opinion of Reddit about the
ICY DOCK Rugged 4 x 2.5 SAS/SATA HDD/SSD Mobile Rack Enclosure for 5.25″ Bay (with Fan Control) | ToughArmor MB607SP-B?

For a budget PC-based storage solution, these 4-bay 2.5″ HDD enclosures are cool. I have one in a spare office PC. I believe with four identical drives, you could use Windows software-based RAID5 (some people diss it, but for budget/hands-on learning, it’s fine), and share out the storage with SMB/CIFS or NFS.

I have the same case! Used 3 of these in the 3 5.25 bays at the top, each slot with a 5TB 2.5” drive in it which gives you 60 TB total. Here are some photos! https://i.imgur.com/hNrN4r4.jpg https://i.imgur.com/C6V49SN.jpg
