Everyone is sharing why not. 24x 3.5 hdd, 40x 2.5 hdd/ssd open airframe case $90 USD at the time with 120x360 aio water cooling with 120mm, 140mm cooling fans. It’s really easy to dust off 
you could use a cs383 silver stone case 
Wendell is currently working on a review of the MSI WS300T60L. He has a “speculation” thread about the 12v3 12pin GPU connector it uses (link). The reason I’m mentioning it here though is that the WS300T60L uses an OEM version of the CS383.
I made a quick post about some of the difference between the two versions of the cases, if anyone is interested.
When I have a bit more time, I might write a more detailed post here.
[EDIT] One thing worth mentioning for anyone who might want to modify their CS383. The MSI has a vented side panel to allow a full height air intake. As can be seen on many glass front and sided cases. Which makes me wonder whether spare case panels might be available from MSI?.. chances are, they won’t even give the time of day to a non-AI company customer but you never know.
