Better sticking to PCB on one side and heatsink on top.
Compare 2nd picture replacement PCB with original PCB in 4th picture.
You’ll notice that the power connector of the replacement PCB has foot prints for two good old 8 pin power connectors on the side of the PCB instead of the troublesome new ones (a lot of RMA issues). :) The 4090 is already a tall card with the power connectors on top requiring even more height clearances for the cable and bend radius. Notice they have power connectors on the side of their PCB instead of the top in their stress test in 3rd picture. I would say those mods are nice.
