A:Answer Hi John,
Thanks for considering us to be a part of your first PC build, we're excited for you! Are you referring to the MSI A320M-A PRO MAX? If so, yes, that motherboard will fit in the SPEC-DELTA RGB. This case supports ITX, micro-ATX, and ATX form factor motherboards. Your motherboard is micro-ATX. For guidance on installation and/or setup with our products, please refer to our CORSAIR LAB channel: https://www.youtube.com/c/CORSAIRHowTo. If you have any additional questions or concerns with the building process, feel free to reach out - we'd be happy to help: support.corsair.com
