Of course, don't use FXO. T/E1 is better.
Use single CPU Machine.
Quad Xeon costs 20 times than a P4/3Ghz/800Mhz FSB Machines. And it is 
only 2 to 2.5 times fatser.
P4SCi from Supermicro is a good MB.
Try to avoid using of IP (SIP) phones - aastra 390/480 with digium card 
outperforms anything.
How much of these 420FXS will be active in the same moment - this is 
critical to designing the system.
420FXS = 18 Channel banks. Spread the system to 6 machines:
Each machine - 3 channel banks + 1 T1/E1 for Incoming in Each machine.
1 Machine for SIP incoming and 1 for all additional stuff - Voicemail ...

And give some more information - how much ACD queues will be, how much 
of the FXS phones will be connected to the each queue ...
