Welcome to the club!
Mine was a 7800x3D build with an RTX 4080. Got the CPU, RAM and Motherboard combo from Microcenter. Built in an H7 Flow case.
Before the build, I’d watched about a million videos on how to build a PC…and when the day came i still chickened out and paid someone to come to my house to set it up for me.
And then the infamous red light on the motherboard. RAM wasn’t allowing the computer to boot. Went to bed disappointed, picked up a 64GB ram deal from Amazon and luckily that worked. It’s been perfect so far.
Only real niggles for me are self-inflicted. I’m using an OLED monitor (2024 Alienware 27 inch) as my primary, and I’m crazy paranoid about burn-in so having to hide icons and toolbars and ensuring it’s turned off anytime I’m not using it. I suspect I’m overdoing it, but…yeah.
