Yep!
My setup is a bit weird now; I have some cases that holster the drives [0], with a low-wattage ATX power supply that exists solely to power the drives. I a bunch of sata male-to-female cables on the case [1], and then a bunch of USB3 to SATA adapters plugged into a couple USB3 hubs into my leader Jetson. I have ZFS On Linux set up on there, and have an NFS share set up on the ZFS mount.
I use Kubernetes to distribute my projects across the cluster, and use NFS for any kind of shared data. It works way better than one might think.
EDIT: Just a note, if you decide for some reason to copy my design, I'm flattered; make sure you either get an ATX power supply that's extremely low wattage or is smart enough to lower the wattage based on load. I made the mistake of taking a power supply out of an old gaming rig the first time I did this, and it ended up consistently using 600W all the time, leading to a hefty power bill one month. I was able to find a power supply that peaked at 200W on ebay for ten bucks, and seems to idle at around 50W, which is much more manageable.
