This feels like it should be a Friday thread. :)

If you’re really going for density:

- At 0.83 inches high you could go 2x per U (depends on your mounting system and how much space it burns)
- I’d expect you could get at least 7 wide if not 8 with the right micro-USB power connector
- In most datacenter racks I’ve seen you could get at least 8 deep even with cable breathing room

So somewhere between 7x8x2 = 112 and 8x8x2 = 128 per U. And if you get truly creative about how you stack them you could probably beat that without too much effort.

This doesn’t solve for cooling, but I think even at these numbers you could probably make it work with nice, tight cabling.
