What should a first-time builder know before assembling a gaming PC?

Take your time and read the manuals before starting, especially the motherboard, case, and CPU cooler instructions. Very few parts should require much force. If something doesn’t fit easily, stop and check the orientation, socket, or mounting points instead of pushing harder.

Assemble and test the core components on top of the motherboard box before installing them in the case. Connect the CPU, cooler, one RAM kit, and power supply, then make sure the system reaches the firmware screen. It’s much easier to troubleshoot outside the case.

Make sure the case has the correct motherboard standoffs installed and positioned for your board. Also remember to remove any protective plastic from the cooler’s contact plate, connect the CPU cooler properly, and prioritize routing the major power cables. Cable management can wait until the system works.

Give yourself several uninterrupted hours and don’t rush when you get stuck. A reasonably spacious mid-tower case with good airflow makes a first build easier, and extra cooling capacity is helpful. Watch a thorough build tutorial beforehand, then use the manuals as you assemble everything.

Don’t feel pressured to buy the most expensive parts. Upper-midrange components usually offer strong performance per dollar, and sales can make a big difference. It can also be worthwhile to consider reputable used parts, particularly graphics cards, as long as you can verify their condition and compatibility.
