Thank you for contacting the Intel Communities.
Regarding the pheripherals that have been tested for this unit, here you can find them: http://www.intel.com/content/www/us/en/support/boards-and-kits/000020804.html?wapkw=nuc6i7kyk
About the external graphics dock, after doing my research, as of now (5/19/2016) the available would be the Razer Core: http://www.razerzone.com/store/razer-core
For future external graphics docks (not known when they can be released), as long as they meet the Thunderbolt™ 3 standard, they should work with your system as well as peripherals.

NOTE: These links (external links) are being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there.
I would recommend that you keep on checking on other external websites (external to Intel) due to the fact that peripherals such as the one you mentioned is a non-Intel product, one good site is this one here: Products | Thunderbolt Technology Community
I would also encourage other community members to share their findings and feedback, that is really beneficial for the community.
Intel is always seeking to provide the best customer experience while using their products, hope you can give the Intel® NUC Kit NUC6i7KYK a try in the future.
If you require any further information or support, do not hesitate to contact any Intel support channel.
I have Skull Canyon, it's good; some problems with audio/video/HDMI but you guys quickly fixing it and that is great.
1. Matched pair-SO-Dimm DDR4-performance memory is very difficult to obtain outside of America, next version please consider going with full size ram. Many Memory distributors OCONUS are not willing to risk stocking SO-DIMM.
2. I saw a photo of a M.2 -> U.2 riser cable on a Asrock Extreme 7+ board connecting it to Intel SSDs; would this riser cable be something compatible with Skull Canyon?
Thank you for the clarification on that OEFVet.
-The use of SO-DIMMs is to keep the form factor meaning the size of the unit small.
-Risers or adapters are not fully supported for the Intel® NUC Kit NUC6i7KYK, Scott_T's comments are applicable for this inquiry for sure.
