For the drives you could get a few big enclosures:

I don't think these offer PMP (port multiplexer) support. I would
look for ones that did if you're serious about doing something like
this.
If you used PMP with 4x drives per sata port, you would only need 9
sata ports in the PC to control the 36 drives. Not sure what the
limits of PMP is, but 4x seems reasonable to me.
