About this site

Planning a small-form-factor PC should not be guesswork

My Mini ITX is an independent resource for compact PC builders. We help you compare outer case dimensions in 3D, look up clearance data from multiple sources, and plan downsizing moves with the AI Build Advisor. Unlike a generic parts list, the focus here is spatial fit: will your GPU, cooler, and PSU actually fit in the case you want on a real desk?

The Case Lab above is free to use without an account. Add any case by name or product link, orbit the models in three dimensions, and stack multiple shells to see volume differences at a glance. Our directory lists over a hundred Mini-ITX and SFF cases with retailer links; the Community forum is where builders share fit notes, thermal results, and build logs.

Dimensions are aggregated from CaseEnd, BuildCores, manufacturer pages, and verified community input. We always recommend confirming critical clearances on official spec sheets before you buy. Case revisions and regional SKUs can differ. Read our guides below for GPU clearance, layout types, and how to get the most from the tools on this site.
