Please buy the case for your B210 - I must have ESD-zapped mine, and am still quite upset by it.
Also, if you buy new from Ettus / NI, you'll get a warranty - not so with the Chinesium clones of this open-source product.
Ettus / NI's warranty picks-up, repairs, and returns like a Dell laptop.
If you put the TXCO on it, you'll have to modify the case, and the crystal housing will poke out the top.
Make / buy an FM-bandstop filter. Avoid the NooElec / Distill FM trap, as its useless >106MHz, which for me has Capital FM received e v e r y w h e r e.
Enjoy - I did.
