Question : ASTERISK HARDWARE ADVICE NEEDED: Connecting 7 Analog POTS Lines to FreePBX Box

I have an IBM x346 server, Type 8840-41U, running the current build of FreePBX.  I want to attach 7 POTS lines to it for redundancy purposes.  Is there a PCI card of some kind that will allow me to do this?  Or maybe an external USB device?  Brand/model gets the points. Thanks.

Fill it up with FXO (Red) modules to recieve lines from the Telco.
