Seeing as the HDD racks apparently cut off any option of using a very high-end graphics card, i can't imagine it being used for anything BUT a home server.
I'm sure only an extremely tiny percentage of users needs 10 HDD's nowadays. But it does have a use. Larger 6 and 8TB drives are disproportionately more expensive than 4TB drives. So if you needed like 40TB of space instead of using 5 super expensive 900 dollar 8TB drives which would be 4500 dollars you could just use 10x 300 dollar 4TB drives for 3000 saving a whopping 1500 dollars. Still only a tiny percentage of home users needs 40TB of space.
Sure, 4TB drives are cheaper, and any decent NAS has software raid z2(hardware RAID6) or z3 config of 6 to 8 hdds, and many use older drives, so its more like two volumes totaling 12-16 hdds, plus maybe 1-2 hdds for OS/OS+VM, and ssd or two for fast caching, so it can be from 12 3.5 +usb to 18 3.5 +2 2.5 +usb and i forgot to add hot spares too. Using this particular case would be a start, but not even close to desired volumes(z2 eliminates 2 hdds, z3 -3 from capacity). Anyone, digging deep enough will know, that software RAID is the way to go.
