When installing structued cabling (Cat 5 or Cat 6) in your home, you
definitely want to consider consolidating the plates as much as
possible. The Home Depot click it together style (I believe you are
speaking of the Quickport jacks by Leviton) is one manufacturers
version that will allow you to mix and match for many different
While their are many manufacturers of these types of products, most
manufacturers are using some sort of click together units to allow for
more universal use. For example, you can install a jack that has a
computer connection, a tv (coax) connection and connections for
speakers or even a baby monitor camera if you like.
As for the cheesy look, all the manufacturers products look fairly
similar. (They were originally designed for offices). But from my
experience, if you use all white jacks, and identify the ones for
computers (RJ-45) - they will tend to blend in to the wall better and
not be such an eyesore.
Hope this info helps.
