Some motherboards today are still providing PS/2 connectors. There are some benefits for gamers but also for those who value security (BadUSB), I use a Intel NUC as a daily driver but I would like to use a PS/2 keyboard and mouse. Are there any options with the NUC?
The only thing I can think of is https://www.gorite.com/ They make a lot of different lids/bodies for the nucs. I looked at their site and did not see anything specific to PS2. You may want to contact them.
