Very impressive. About the only limitation I saw (and probably the reason it appears a little smaller than the old cheese grater) is it doesn't have support / space for Hard Drives (4TB in SSD's is the largest internal configurable option it looks like - gotta guess that would be an eye watering price).
I do like that they obviously embraced the cheese grater nickname of the old towers.
I'm with you ElectriPotato, if this started at $3k or $4k I'd be able to lift it. Will make my last version of the original cheese grater last a a year or two more then probably land in an iMac - which I've waited to avoid.
If you check the accessories list on bottom of the Mac Pro page.. There’s a 32TB MPX card option for storage.
