Most of the units I've seen (I've accumulated quite a nice
collection! :> ) have the connectors *peek* through the slots
in the front metal plate, mounted from behind.
For example:
<http://www.genesistems.com/office/pics/PatchPanel.JPG>
Note the "black dots" -- each a boss/stand-off that's supporting
the PCB onto which the individual connectors are mounted.
Or:
<http://www.showmecables.com/product/Cat5e-Patch-Panel-48-Port.aspx>
which has some alternate thumbnails showing detail of the
openings in the panel -- along with a view of the back side.
E.g., a PCB (or, a set of PCB's) is mounted behind the panel.
On one side of the PCB, the connectors are mounted. On the reverse
side, a series of punch-down blocks (the third thumbnail) which
are connected to the connectors via traces on the PCB's.
Viewed "end-on" sighting down the row of connectors, you have:
CCCC
==========
B B
where CCCC represents the connector's body and B the punchdown
blocks.
But, the epiphany is hidden in your phrase: "a small lip to cover
minor flaws"! I.e., while the connectors themselves don't have such
a lip, there's nothing to prevent me from *making* one!
Specifically, creating a "precise" veneer to mask any ugliness
in the fabrication of the "metal/lexan panel". I.e., use the
panel for structural support and adhere a thin (rigid) plastic
veneer *to* it!
You could precisely cut the slots in that veneer with a good
straight edge and sharp xacto knife. Heck, you could even
make it out of an exotic *wood* veneer: "Be the first on
your block to have a Mahogany patch panel!" :>

With the veneer approach, you could be *really* crude in how well you
cut the slots. And, "filing" would only be necessary to remove burrs,
etc.
Yes, I like this idea! It's something that others could easily
reproduce and get "good" results -- all while avoiding the need
to locate some "service" to do the work for you!
