You don't need a huge toolkit to build a PC. But a clean workspace and a good dose of patience really matter.
Must-Have
- Phillips screwdriver
- A clean table
- Good lighting
- Motherboard manual
- USB drive for OS install
Nice to Have
- Cable ties / Velcro ties
- Thermal paste, if it doesn't come with the cooler
- Small tray for screws
- Flashlight
- Anti-static wrist strap, if available
Safety Habit
- Unplug the power cable
- Don't build on a carpet
- Hold parts by the edges
- Keep liquids well away
- If it doesn't fit, don't force it
You should see
Patience matters more than any tool. A PC build rarely needs force — most of the time what it needs is proper alignment.
