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!

Why not VMs? Dell poweredge fx2s with 4 x fc630 or any other multi-node server will not only give you density but also the ability to scale out with the option of just turning off one or more of the nodes. There's also the Hyve Zeus 1u servers that run pretty quiet, and can also scale out depending on how many you have turned on. They're absolutely no-frills, only has room for two 2.5" drives, but it's supermicro-based so there's plenty of documentation.

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.
