While I understand the PCB was sized to mount in this case, and it does fit well, I have a question regarding cable egress (in and out).
Trying to get 4 or 5 cat-5 cables in and out of that small enclosure is fairly difficult, and does tend to crimp the cables, especially with the top entry and the cover closed.
Luckily, I was able to keep my splitter indoors and have the case open.
I'll be looking for an alternate way to package this next year if I put a splitter out in the yard.
