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!

I just happen to have a spreadsheet that covers compute density for all models of dell, HPE, and supermicro...

Your cost/density sweet spot is going to be the 2u/4 node platform from Dell or supermicro that use the xeon e5-2600v4 or scalable v2. There's a wide selection on eBay for this stuff, so it's definitely available. At 16 cores/CPU, 128 cores/2u unit, you'll need 6 units.

For the dell fx2s with 4 x fx630 nodes, 256gb memory/node, 32 cores/node, I spec'd one out for $2400 before storage and GPU
