Select components, see them assemble in a scale-accurate 3D environment, get instant compatibility checks and live pricing from PCPartPicker.
3D PC build environment — assemble, inspect, customise
From first-person 3D inspection to real-time compatibility checking — all in one app.
Every component is built to real millimetre dimensions — cases, GPUs, coolers, fans, and more render at true scale so you can verify physical fit.
Parts data is pulled live from PCPartPicker on launch — current prices, stock availability, and buy links all in one place.
Instant checks for CPU socket, DDR type, GPU length, cooler clearance, radiator size, TDP headroom and PSU wattage — errors shown before you buy.
Split the build apart with a single keypress to inspect internal layout, cable routing space and cooling airflow paths.
Store multiple named builds locally. The app auto-saves your last session so you never lose work between launches.
Capture your finished build as a high-quality PNG directly from the 3D viewport with one click.
Core build components plus peripherals and accessories — plan a complete desktop setup.
The built-in rule engine checks every critical pairing the moment you add a part.
