Question Upgrade recommendations.

[Energizor]

Hi, I have the ASUS ROG Strix G15CX Gaming Desktop from best buy with all the stock components and I am looking to replace the motherboard. I believe the stock motherboard is LGA1151 MicroATX. Do you guys have any suggestions?

why do you want/need to replace the motherboard?

that isn't a motherboard model, just a type and size.

since this system is some ASUS OEM edition then you will need to determine if this case and power supply even support retail spec boards.
if it doesn't; then you may need to contact ASUS support directly and see what upgrade options they offer.
