Before You Buy This Desktop

It is a practical choice for multitasking, provided you accept the older processor architecture. Regularly update your drivers and Windows 10 Pro to maintain security and performance stability over time.

Check before you buy

• Confirm your monitor has DisplayPort or VGA input.
