“What parts should I buy for this budget?” is a different question from “my PC won’t boot.” r/buildapc is the large custom-desktop advice community, but full spoon-fed parts lists are steered to r/buildapcforme or Discord. Broken-PC troubleshooting still belongs on the computer-problem page.
Where to ask
Best for: Custom desktop build discussion and single-part questions — not full spoon-fed lists or laptop shopping.
Why it fits: Its public description: “Planning on building a computer but need some advice? This is the place to ask! /r/buildapc is a community-driven subreddit dedicated to custom PC assembly.”

Rules to know before posting:
- Be respectful.
- No full build-spoonfeeding requests — complete parts lists go to r/buildapcforme or the Discord; single-part questions are fine.
- No piracy or grey-market software keys.
- No laptop or prebuilt shopping questions — use laptop suggestion communities instead.
- No hardware-news dumps, sales posts, retailer-RMA vents, all-caps/clickbait titles, low-effort memes as submissions, self-promo, selling/trading, or more than one submission per 24 hours.
- No intentionally harmful or joke advice; no bots; ban appeals go through modmail only.

Before you post
- State budget, country, resolution/refresh target and whether the PC is for gaming, video or general use.
- Laptops belong on laptop-suggestion communities; boot failures belong on the computer-problem page.
- Complete “build this for me” lists need the buildapcforme template — not a vague budget-only title on buildapc.
