I've seen cards (including one that used an X1 slot and a number of USB cables to create an external X 4-8-16(?) slot array. Aimed at bitcoin miners (which I ain't!!!).

What I want is to increase the # slots I have on a mobo for additional cards. Specifically, I want additional pcie slots for utility cards, like USB.

BUT what I really want is for these to work on early Cheese grater mac pros, 3.1 and 4.1...which are pcie gen2 ( or gen 1 in the 3.1).. Don't need to bump up the Gen, but these boxes only have 4 slots and video cards able to handle current OS take space of two slots. So...hoping...<G>

Anyone have hands-on with something like this. (my cheese graters are running Catalina with help from drdos (I think).


Or maybe I should have looked for a macintosh group (didn't think of it until now...sorry<G>)
