Model ASUS Zen AIO ZN240ICGK-Ra030t. Hello. Can I install a second SSD on this model? or just a replacement instead of HDD?
No, there is only one SATA connector on the main board and there is not enough space to install a second disk. However, you can easily replace the original installed SSHD with a 2.5-inch SATA SSD drive.
