Personally I'd go for the MSI. The color scheme is awful but lately Asus low end stuff seem pretty unreliable. From a connectivity standpoint the MSI has more sata drives and less usb 3.0 which for my personal taste is better. The M.2 slot on the asus is essentially another ssd on a stick and nothing more performance wise.
Between the two I'd go MSI. I would also check the Gigabyte UD series if it is in your budget.
