Discussion herehere relates to questions being on topic on SuperUser, and therefore not here.
I suggest adding the following as a custom close reason:
"Hardware Recommendations" was created for questions seeking a specific hardware products given a set of definitive requirements. If your question involved general computing or hardware issues, it can likely be asked on Super User; but nevertheless, it is outside the scope of this site.
This will help refine the site scope even during the private beta (but especially in the public beta, which we hopefully will achieve).
