THE INTEL NUC is at the forefront of small form factor chassis, and also has the bonus of being supremely easy to build in. After all, it’s more than just a case—it’s a bare-bones kit that comes with most of the pieces pre-installed to save you some of the hard work. However, these cases don’t come cheap, especially the topof-the-r ange i9-powered Intel NUC 13 Extreme. There are far cheaper options available, including some so small that you can even mount them to the back of your monitor.
