Hey everyone! I'm putting together my first PC and I'm feeling a bit anxious about the whole process. I've already bought my parts, including a PNY 12GB 4070 Super GPU, a 9700X CPU, and a B850 Tomahawk motherboard, finding them at good prices. Most of the other components are en route or will be purchased soon. My main concern is whether there are any common pitfalls that first-time builders might overlook. Is the thermal paste that comes with the cooler usually sufficient? Can I rely on the stock fans with my case (I'm looking at the 4000D Airflow), or should I plan to replace them? What about using the stock cables? Lastly, will a regular screwdriver and bit set suffice for assembly? I know it sounds like a lot, but I really want to make sure I don't miss anything important since it's a big investment!

Honestly, I’d suggest skipping the 4000D. Look into an Antec C5 ARGB; it's packed with fans! Or the Phanteks XT Pro Ultra if you're not into that fish tank look. Those models are well-regarded and might serve you better in terms of cooling.
First off, don't forget to pick a solid PSU, haha! Make sure to input your build into PCPartPicker to check your wattage needs and compatibility. As for fans, I’ve used the stock ones in my Fractal case and added a few more for better airflow. The thermal paste included with your cooler should be fine for starters, but if you want to upgrade later, just ensure it’s non-conductive. Avoid liquid metal unless you’re okay with the risk of shorts if it spills!
I did a deep dive on PSU ratings too and ended up with a 650W for my 430W build, which gives me room for future upgrades. Definitely keep an eye on temperatures and consider extra fans down the road if you need them!

Thanks for the suggestions! I’m curious if the fans are the main reason for your preference—always looking for the best airflow!
