This is probably off-topic here, but for a competent engineer the RF noise 
in a PC is not a big problem.  There are many pro-grade sound boards that 
have the converters on a PCI card, and there's no metal shielding on the 
board.  These boards often run 24bit/96kHz and get quite good S/N.  A 
Faraday cage isn't needed, just good smart board design.  There will 
always be an advantage to having analog stuff in its own shielded 
environment, but it's only an issue if you need more than, say, 100db of 
dynamic range.
