Builds

Parts lists with compatibility checks and clearly labeled test status.

All builds

What actually fits

Find the parts that fit your space, starting with the case and graphics card.

Filter by the numbers that actually decide a console-sized build - case volume in litres, GPU length and thickness in millimetres. Those are the walls you hit at 10 litres, and they are the ones you are left to work out on your own everywhere else.

Every dimension here was read off the manufacturer's own spec page, and each part says which page, and when. Where a maker publishes no figure, the catalog says Not published - it does not print a number we made up.

Guides

The answers behind the compatibility checks - what fits, what boots, and what to buy instead.
