Does anyone know of an available XLR patchbay?

I'd prefer to purchase one before resorting to building it.

I'd like to maximise my work flow and connect my pci audio interface to the patchbay, making the swapping of instruments/vocal inputs a little easier.

Any wisdom is appreciated.

I just did an upgrade and rearrangement of my studio & am sitting here wondering if anyone uses XLR patchbays for mic preamp's? Is this a common practice or unadvisable from a fidelity standpoint. It certainly would be a hell of a lot more convenient than repatching mic cables all the time.
