It’s been 20 years since I built a computer from scratch. And that was with help from my dad, whose been messing with computers since the 70s (the Radio Shack TRS-80!).
So it was with some trepidation that I got started on my custom desktop build.
I used Claude.ai as an advisor throughout the build. From choosing parts to the final Windows tweaks, it was my guide. When I started exploring this idea, I was able to use Claude’s Fable 5 model, but as soon as I started building, the US government put a damper on it. Through most of the build I used Opus 4.5, but I suspect this would have gone better with Fable 5.
Are you considering using an LLM AI as an advisor on your build?
Here’s what I learned from my experience. The good and the bad.
The good: A Desktop Computer Designed for Me
The standout benefit was that I didn’t end up with a generic build.
I told the AI how I actually use a computer: a browser with a dozen tabs, extensions running in the background, the occasional video edit, along with what I wanted (small, quiet) and what I didn’t (a pricey graphics card I’d never touch, a tower the size of a filing cabinet).
Claude took all of that and designed a system around it, steering me away from money I didn’t need to spend and toward the parts that mattered for my work.
It was patient. I could ask it things I probably wouldn’t have bugged a person with. Whys and whats and clarifications.
I sent photos constantly – of parts, of where a cable was supposed to go, of the inside of the case mid-assembly. Claude used them to tell me where I was, identify components I couldn’t name, and catch mistakes.
When something went sideways, I got step-by-step troubleshooting on the spot. On the first boot up the machine wouldn’t power on at all. Claude walked me through checking everything and reseating each connection. I’m still not sure which connection was the issue, but afterwards it booted right up. It explained the reasoning behind its advice, too, often too much.
The bad: AI’s Are Optimists!
Now the part nobody warns you about.
An AI is relentlessly upbeat, and that has a cost.
It tends to make things sound easier than they are. Steps that ate up an hour were pitched like they’d take five minutes. It quoted prices rosier than what I paid at checkout (Claude’s pricing info was outdated).
And every so often it was simply wrong. In my case nothing was catastrophic. A missed step here, a confidently incorrect detail there. But it was enough to cost me time and test my patience. You can’t switch your brain off. Treat its confidence as suspect. Double-check anything involving money or a step you can’t undo. Youtube also came in handy when there was something I wanted to check on to see how other people did it.
Worth it?
Despite some grumbling, yes.
I went from a pile of boxes Saturday morning to a finished, customized Windows machine ready for work Monday. Two days, no recent experience, no in-person help. The AI got me there faster than any stack of forum posts could have.
If you are building your own using an AI as a guide, Just go in clear-eyed. It’s an amazing (Claude would say “a brilliant”, but I wouldn’t go that far), tireless assistant that occasionally oversells.
Bring your own skepticism, and you’ll do just fine.
