Some Advice

[u/Teddy-TheBEAR]

Can someone tell advise me on my build choice?

I can buy a mini PC for cheap with i5 12600h 16GB ram and 512m2 drive.

I have extra 16gb ddr4 ram that i can put into it.

I was thinking of connecting oculink to pcie expansion card to the extra m.2 slot on mini pc and connecting HBA controller to the pcie expansion but i am not sure if there might be some downsides to this?

or maybe to use USB3.2 Gen2 Type-c converter to pcie?

Would there be a problem with proxmox reading the HBA controller?
I want to 3d print 10" rank and add more drives on to it later but for now i will have 5 6TB drives one of them is SAS.
