Whatever works for you. If you remember, my last PC was a pre-built that I bought from Costco. It was OK...but just OK...it had its share of issues that I ended up having to fix.
This PC, I built.
Precisely why I roll my own, I don't have PC issues.
FWIW, I've been ship-of-theseusing my own computer for about 25 years now. And my dad basically begged me to build him a system.
But honestly, I think there's a big difference between "I assembled my computer from parts" and "My hobby is building PCs."
Like, I have hobbies, and I spend a fair number of hours per week pursuing them. But that's the problem - no way I'd ever need to spend 10 hours a week worrying about which video card to buy when I only get one every 4-5 years. It's insufficient intellectual stimulation to constitute a hobby.
DIY in 2024 = Legos. It isn't a hobby, it's a means to an end. PC gaming is the hobby. VR while you can do it stand alone is best with PC too. Hell, you can even get a great workout, thrill of the fight and beat saber are my favorites.
People that build as a hobby usually do it like Etsy, where it's more of a side hustle for fun money and or to support the hobby itself.
As to the 10hrs a week hyperbole: Intellectuals just post for build help in general hardware and some of our absolute legends will provide a bunch of pcpartspicker lists that fit your budget to choose from. Boom done.
Next PC of mine will be a pre-built. I'm currently on a gaming laptop, that I got on a fairly excellent deal ($699 at WM).
Don't cop out and buy some boring Walmart piece of shit. Support one of the tech tubers you watch like Toasty Bros. I'd be interested in reading your experience.
Reading this on forums started by a kid into PC hardware is depressing. You may have lost that loving feeling but one need look no further than r/PCMR to see there are legions of young ones to take your place. Yeah, desktop is only 20% of the PC market, but that is still 9 figures. And those old office boxes don't all end up e-waste. Pimping them out and selling them as gaming PCs is a whole cottage industry unto itself now.
