is there any place you know where this motherboard is available now ? I've been checking on all major shops and they're all out of stock. This Asus model is really attractive, it gives much more space to the pcie slots, with my current mb it's really difficult to put all risers next to each other due to the lack of space.

For those who already have it, do you measure performance differences between the different slots available? I have a 13 pcie motherboard and I have 3 underperforming slots.

If you use risers that have the USB cable come straight out, clearance is not an issue at all.
Right-angle risers you have to use in the "closest to the power connection" slots if you are going to use more than one riser per row. or you get cable interference that can make reliable seating of the riser "interface board" problematic.

There should be no performance difference between the slots - try swapping your risers around to see if the issue follows the board.
I've had issues where a "performance difference" turned out to be a marginal USB cable, and just replacing the cable with a better cable CURED the issue.
