Need to add 50 micro-pcs to my homelab (dabbing in AI / clustered computing) - Seeking advice on how to rackmount. (alien.top)

Hello all,

I'm going to be adding 50 micro pcs to my homelab, something similar to this: https://i.imgur.com/SvVeHLu.png Each unit is roughly 4.5 in x 4.5 in x 2.5 in and has hardly any weight to it.

I'd like to find a way to rackmount these in the most space efficient manner. For example, having each of these units slotted in from the top/down, similar to this mock-up I made: https://i.imgur.com/zRc4b7G.png

My research so far has shown me this: https://i.imgur.com/AWznyB5.png which is a simple rackmount on a slider that is metal. I imagine I could maybe build some sort of support framework on top of it to handle sliding things in, albeit I am not entirely sure how. Maybe I could 3d print something.

Would anybody have any ideas on how I could build a server rack that would support something like this, ideally something that is on slide-out bearings?

Note: I have a pretty healthy budget to buy whatever or modify whatever, so that should help option some options.

Thanks in advance!

From a cost to performance perspective, I don't believe the solution you mentioned would be very attractive. For example, what I am looking to build, would be 700 pretty fast physical CPU cores (4.4ghz) @ $23k (and more cores/speed, for incremental price increase). I haven't found any server solution, used or new, which can compare to that in raw processing power.
