Would you please share a link to your chassis and risers? I have the PCIE lanes, but not yet encountered a reasonable way to have more than 3 GPUs directly attached to a host, both from physical space and power requirements. External PCIe switch cases are not reasonably available to mortals :/

Just search amazon for "pci4 riser" and you can get them up to a foot long. Any sort of mining frame will do. Power is a bigger issue. Running multiple power supplies is something i know about but have not done personally. Nor do i want to. Im happy keeping everything on one circuit.
