I'm unhappy with the spacing between the PCIe slots, since many graphics cards are dual slot cards, which means that only the lower slot could be used without obstructing the other ones. Then there's the issue with ventilation, if, for example, you choose to use the remaining slots for 4x or 2x nvme adapter cards (4 times or 2 times 4-lane nvme cards). That huge limitation only for the smaller form factor really hurts.
