If anyone selects the excellent Pi/DRAWS case from C4Labs:

 

https://www.c4labs.com/product/nwdrpi-2-for-raspberry-pi-3b-3b-2b-b-and-drawstm-digital-radio-amateur-workstation-version-2-hat/

 

... and would like to add a top to help guard against RFI (as demonstrated on YouTube by KM4ACK: https://www.youtube.com/watch?v=QZqh_Rc1s9s&t=7s), I just wanted to share that in addition to aluminum, a spare piece of copper PCB material can be fabricated into a decent top.  

 

73!
