I don't know how to put it into words, but this aesthetic of computers just looks sooo good.
Makes me want to try making my homelab/experimental hardware look like it.
Any ideas how to source parts that look similar in low quantities?
Yeah, eBay has tons of them. Use them for movie props all the time. If anyone is in LA there are plenty of surplus electronics shops that are overflowing with them. I used to search "cannon connectors" IIRC.
The steel ones ("Cannon connectors") are indeed very expensive: the only ones I have were removed from industrial equipment. However, for hobbyist use, I'd buy CPC -- Circular Plastic Connectors. Those are available in the same variety of pinouts and cost an order of magnitude less.
