Reddit mentions of Bplus: P14S-P14FP, M.2 (NGFF) to PCIe X2 Edge Extender Board

Yes, I know the monitor sucks. I still have it only because it's touchscreen and therefore good to keep on my desk with the soldering iron and other tools that are best kept away from keyboards/mice. Issues: Other than the PCIE bandwidth with that particular adapter, I noticed that the sound over HDMI was spotty and would cut out.

Lessons: I need to find an M.2 to PCIE adapter that carries more/faster lanes, but really only losing 50% performance using only TWO LANES of PCIE 1.1 bandwith shocked me. I expected to lose a whole lot more. Also the Intel Iris Pro in the NUC blows the doors off Intel HD graphics in the i5 4690k. If not for the tremendous amount of power lost to the M.2-PCIE bottleneck, this would certainly be a playable level of gaming at 1080p if I can build an enclosure for it. For now, the GTX 970 is returning to the Haswell system and I am going to continue to use that as my steam machine until either I can build something smaller/quieter (too bad I built it before Bulldog was available) or an affordable Thunderbolt 3 eGPU enclosure hits the market. I might try to get the 3D printer working again and make some sort of enclosure when I get the speed worked out.

edit line breaks, fixed a url
edit 2 I just realized I'm not the first person to put an external GPU in an Intel NUC. Someone on imgur put this together 11 months ago: http://imgur.com/a/JHoIy I have no other information on that other than the imgur post, but WELL DONE other hardware hacker!

They do but it seems like you have to try your luck and see if it works.

I found that new AM4 itx boards (including Asrock x370, Asrock AB350, Gigabyte GA-AB350N) has M.2 socket on the back, so it's little tricky to install this adapter, because it's higher than the gap between mainboard and case

Take little search and I found this of a guy on /r/pcmasterrace. So the solution for us is: Bplus: P14S-P14FP, but unfortunately it's currently unavailable and seem that it will not being production anymore.

But Bplus (the vendor of above product) has new product and look like it's more flexible and promising. Currently I can not find it's being sold anywhere, I will try to contact them to get one and we will see it works or not
