Hi, thanks for $0 advice 
. The desktop I run blueiris is i5 6500 HP 3.2 ghz Amazon.com
My only concern is that I have to dedicate resources for the VM to run in parallel with windows which may impact the performance for both. I use deep stack with blueiris so no need to have in HA. Also my assumption is that the NUC will run on HA OS not as a VM which will eliminate the dependency of windows updates/ restarts. No sure if this is a dimension which has to be considered or not as HA also requires updates and restarts specially recently
