A:AnswerYes to vapor chamber, and you don't need DDR4 2400hz RAM, installed is 2133hz and the benchmarks for the differences is rather insignificant at 1% increase in speed and a 3% drop in latency. This however is not the case in server RAM configs, where there is a 8% difference. However for PC and laptop settings, you can swap out the 2133hz for 2400hz and spend about $320 doing so to only find out there is no noticeable difference in the environment used :)
A:AnswerVR ready yes, Blu Ray No, DVD yes. Just grab an external USB 3.0 Blu Ray drive for under $100. Nowadays, most just stream Blu Ray, or simply have a Blu Ray receiver for their home theater to watch. However, for $100 bucks, problem solved.
