Another option instead of 2 servers dedicated as PRI gateways is to use AudioCodes Mediant 1000 or 2000 gateways. Either of them will also failover to a backup proxy if the primary proxy (server) is offline. Probably much cheaper than the kick ass box you plan to build + PRI card(s).
I'm not affiliated either, but we do place them in our 911 call centers. They have analog gateways as well for FXO & FXS devices.

They have good products. I am not affiliated with them, just a happy user on a couple of deployments.
