Can I upgrade motherboard in current PowerSpec tower?

@bobfake Good morning and thank you for your question. If you're choosing the same size motherboard you can do this in most systems including this one. You would need to upgrade both the Motherboard and the CPU, but the RAM as well as this system uses DDR3 rather than current DDR4 which uses a different socket type. 

If you're looking for suggestions on parts to choose based on the performance that you're looking for, I'd check our how to choose parts section. https://community.microcenter.com/discussion/3311/how-to-choose-parts-for-your-custom-computer-build/p1 If you have any additional questions, our Sales Consultants would be happy to assist in store at our Build Your Own PC section with no appointments required. I hope this helps!
