A:Answer JW22,
Thank you for your interest in this Rhodium system!
The system is certainly upgradeable, and modifying the configuration over time does not void the warranty or Free Lifetime Technical Support that we provide.
As to your question regarding video editing, it is capable, but a more in-depth will depend on other factors, primarily what software you plan to use.
So that we may better answer your questions, please contact our Friendly Customer Service Team, toll-free, at 855.490.2569. Whether this Rhodium, or another of our offerings here at Best Buy, we'll help you find the system that's best for you!
