The three questions we hear most often about this build and who it's for.
Check the compatible models table. Anything up to 13B runs smoothly. 32B+ models work in Q4 quantization, with slower responses on budget hardware.
It's excellent for personal productivity and prototyping. For shared production workloads or enterprise SLAs, step up to the Premium build with RTX 4090.
If you've built a PC before, plan ~2 hours. First time? Budget 4 hours and follow our assembly guide. All parts are standard ATX with no proprietary connectors.
