An aesthetically pleasing small form factor desktop computer is described. The small form factor desktop computer can be formed of a single piece seamless housing that in the described embodiment is machined from a single billet of aluminum. In some embodiments, the housing includes a fastening system for securing and electrically grounding internal components to the housing. Fewer components and less time and effort can be required for assembly of the small form factor desktop computer and the absence of seams in the single piece housing can provide good protection against environmental contamination of internal components as well as EM shielding.
