I'd sell the board and buy a Threadripper motherboard, which actually HAS pci-e lanes to throw to the pci-e slots. 80 pci-e 4.0 lanes spread across 4-7 pci-e slots + m.2 connectors + bifurcation support + ecc support + 8 memory sticks...
 
As for what to use pci-e slots .... extra video card, hdmi capture card , SDI/other input capture card, SCSI controller (for some tape drive backup that's older and doesn't use usb, or for scsi drives) , extra sata/sas controller if more storage is needed, higher end sound card, extra thunderbolt cards if supported ...
 
 

Work in progress. GPU blocks should be here Saturday, so hopefully finish the loop this weekend or early next week.



copper will eventually be painted / powder coated, playing with paints

I plugged a 4 pin floppy connector into a CD aux connector on a sound card when I was quite young. The blue smoke that made the sound card work escaped.

Getting high profile ram....I have to bend it quite a bit so that my cooler's fan can fit.
And I have accidentally kicked my case a couple time.
