My best guesses (that I would be excited about): - A carry case / protector for the case - Thinner Mid-plate to allow for either more GPU thickness or CPU thickness clearance (personal preference: GPU thickness ) - More vents on the metal panels? -fingers crossed- - Completely mesh side panels - Something I/O related...? ( A very subtle type-C port for example...) My secondary best guesses (of things that wouldn't tickle my interest ) - Something to do with HDPLEX - Anything to do with a handle - Anything RGB related (I like to implement my own lighting ) Yes, hopefully something can be done, I appreciate this will also affect the timeline since you may have to produce more prototypes after the first non-youtube sampling since if there are issues found, then you will have to produce new prototypes for the youtubers. Having said that, this is significantly better than some issue being exposed on youtube and receiving bad press, so personally Youtube reviewing should aimed to be a "free ad" rather than a troubleshooting sesion. Obviously the non-youtube sampling would have to be done to those who can commit on effectively a NDA to make sure you can quietly fix the issues as well as people who have complementary hardware to test in the system. I would say if it helps at all, maybe you can request for the internal "reviewers" to return the cases afterwards in the case that they are flawless and can be sent directly to youtubers afterwards.
