<p align="center"> <img src="final-build.jpg" width="400"> </p>This is a guide on how you can build a low-cost (<1,300€) AI computer by yourself to run your AI flows locally.
Ideal for students on a low budget. The build can, of course, also be expanded and constructed in a way to offer the best performance for enterprises, for example.
