About to build my very own PC for the first time.
I’m very excited!!!

Step 1: motherboard is in

RAM & CPU in, doing the cooler now.

My fingers are covered in cooling paste

GPU & SSD

PSU is in! I’ll do something about the cables later, first turning it on!

Omg everything seems to be running!!
Love the lights
Trying on a monitor next

Not getting any image on the monitor (tried both HDMI ports) so currently trying to figure out what to do next.

Still troubleshooting - it also doesn't beep, which is concerning. I think it might be the CPU.
(thanks everyone for sending suggestions!)
