First post. I was looking at the install manual for the VK-3...
Given that you're demonstrating a rear-mounted NVMe slot on the diagrams, these types of motherboards appear safe - but are they actually functional as opposed to just not interfering with the riser cable installation? No plans currently on installing there but would like to know if there is an opportunity.
Also, is fan support on the VK-3 strictly 80mm x 10mm thickness, or 15mm allowable?
Edit: My forum title is funny yet depressing at the same time
There is space for M.2 on the back side and maximum fan thickness is 10 mm.
