Show HN: Build a PC in 3D in the Browser

BuildCores lets you plan, preview, and price a custom PC entirely in your browser using interactive 3D. Browse 5,000+ 3D models and 50,000+ parts, check compatibility as you assemble, compare live prices across retailers like Amazon, Newegg, and Best Buy, and estimate game FPS and power draw before spending a cent. Visualize airflow, modularity, and RGB lighting, or place your build at scale with AR. With quick-start templates, community builds, and a free tier that needs no account, it removes the guesswork from PC building.

Build it before you buy it — know how your build will look, fit, and perform before you buy a single part.

    Why are so many gaming parts made with annoying leds? I wouldn't mind having a case with a transparent window in order to quickly check if said computer needs a cleanup but those lights are so annoying this is a no go.

    I could disable most leds from my mainboard settings but not for my gpu. I can turn off the lights of my cheap mechanical keyboard with a shortcut but they always turn on by default when I turn the computer.

    Is there a database of parts without stupid lights included by default? It should be the norm but it seems it has become rare or you have to pay a premium or install conpanion apps to be able to turn them off by default..

    interface feels quite cluttered

    This looks like a simple idea executed PERFECTLY.

    Shared with a few people I know - and I will refer to this instead of "asking my bro" about techy hardware stuff.

    Since i personally have a VISUAL learning style, this is right up my alley.

    good hunting + best of luck with this.

    ps. I adore the website design + messaging too. 10/10
