Just transferred some existing hardware to a new 8-bay mini-ITX case (Silverstone DS380B). Filled it up with 6 x 6TB Western Digital REDs for 36TB of mechanical storage.
I'm pleased with the case. It's pretty well made, even though not necessarily high-end. Used an old SFX PSU with a low-voltage Intel Core i5, 4GB RAM.
Not proud of the cable management (i.e. there is none!), but I'll go back and clean it up when I get more time. Setting up #ZFS
ZRAID2 right now (think: RAID 6) for a total of 24TB-ish space!
