Want to show one great PCIe expansion card for #HomeLab|s
This card here allows to put 4 NVMEs into a single half-height PCIE x16 (or two in x8; 1 in x4) slot.

Two go on the front and two on the back. The ones on the back MAY have clearance issues depending on how large the cooler on your NVMEs is. However as you've to slot it into a x16 slot in order to use these two anyway you're probably slotting it into the top most one so there shouldn't be another card in the way

@raito see 2nd post, also don't all mainboard have that these days? I can't remember when I last encountered one that didn't.

@agowa338 pcie bifurcation is expensive, card with pcie switches exist to make up for that, they're just more expensive

@raito I have never seen PCIe switch cards sed to split up larger ports. The only ones I've seen was to add more ports. Like e.g. split a single x4 into 2 x4 and similar...

(If only the 1st NVME is detected you've to manually set the port to x4x4x4x4 aka. x4x4 PCIe-Bifurcation, "Auto" didn't work for me)
