Considering the parts aren't made out of paper, no it is quite hard to 'break them'. But I would recommend you do these following things
Ground yourself to the floor so a static electricity shock cannot occur and damage your components ( e.g. motherboard etc.) You can do this by laying the motherboard on the box that it came in, and slotting in your parts on that, also, you should be barefoot while building, only if you have a wooden floor/floorboard, this recues the risk of you building up charge of static electricity, try your best not to build on carpets as they can generate static and can damage your hardware. If you only have carpets in your house, you can buy a anti static wrist strap, which is like 2 dollars, you attach this to your wrist and the other end to your case, ensuring that any electricity is gone from your body, or just attach it to your leg and let the other end touch the floor.
