Has anyone ever tried to open up one of these filter

ones I've seen seem to have the cases soldered closed, so they could be

Yes and yes :)
I can't for the life of me remember why I took one to bits now, but I did at
some point last year. All potted inside, with no PCB or anything and
components just soldered directly together.
