I don't like my black lid ... I want to replace it. I see a lot of replacement lids for sale, but I don't see a clear one. I think it would look pretty cool!
You could 3D Print your own clear lid. There are templates available for the lid. For more information, start here: https://www.intel.com/content/www/us/en/products/docs/boards-kits/nuc/nuc-replaceable-lid-dxf-step.h....
FYI - I personally don't think that this is a worthwhile effort, however. There's a metal plate between you and the innards of the NUC, so not much of a view inside.
Thank you for posting on the Intel® communities. We hope that the information and links provided by the community have been helpful.
Also, it is worth mentioning that Intel® doesn't manufacture custom lids. They are manufactured and sold by third-party companies or partners. Having said that, we recommend addressing this "feature request" for a clear lid to the different manufacturers or our Intel Innovation Partners (GoRite* and Simply NUC*) so they might consider this request.
