Only a Phillips screwdriver is needed (for motherboards, hard drives, and CD-ROMs are all tool-less), and the case comes with its own screws
Personally, I don't think the biggest problem is the tools for a novice, it's the connection between the motherboard and the expansion ports and switching lights on the chassis
But it's not hard to spend time researching
This is the first time I've ever seen the motherboard and the expansion ports and switching lights in the chassis. Good luck to the owner
