Crashman :
Uh, MJ, you do know that we frequently review motherboards with open-ended PCIe x1 slots, and that Intel even had an open-ended PCIe x4 slot with a separate hook bracket for the end of the card on one of its boards (back when it had boards).
So, I think the presence of x16 slots was just to get you to notice. And that worked. But it created more problems than it avoided, as most competing boards can support at least two M.2 drives including at least one 110mm M.2.
Hey Tom,
Yea, I was aware that often companies use open-ended x1 ports to support longer devices, but I still like this setup. It would hold longer cards more securely, and I suspect it would be easier for novices that can assemble a PC but don't know x16 cards would work in an x1 slot.
I actually need to update this soon as I found the actual connection on each slot. Surprisingly none of them are x1, they are all x4 or greater.
The M.2 slot bit is a bit of an issue. The one M.2 it has is limited to 80mm drives because of heatsinks used to cool the M.2 SSD. But really this board could have used another M.2, and they probably should have left that 2nd PCI-E slot off to make room for a second M.2 slot that can support 110mm SSDs.
