Re: Please help me build my first PC!
You’re going to be short on power. That’s a powerful system for a Pico. The Ceton card alone is said to use 25W. And you don’t know which voltage that is pulled on. The Pico provides very little power on the 5V rails. The Pico is a cool PSU, but I would recommend you walk before you run.
Fans in your system can be extremely quiet if you pick the right ones, optimize airflow, and enable fan speed control. Don’t shy away from fanned power supplies. There are some that are incredibly quiet. Check out SilentPCReview for their latest recommendation on power supplies. They won’t steer you wrong over there. The rest of the build seems great, if a little ambitious for a first try. I’m not sure you need 8GB of ram coupled with a SSD, 2GB is enough for a dedicated HTPC, but it can never hurt.
