That machine is a strange combination of the June 2004 and the late 2004 PowerMac G5 that doesn't exist.
This makes it a June one:
PCI-X slots
2.5Ghz clock speed
8GB of ram
This makes it a late 2004 one:
ModelID of PowerMac9,1
Model number: A1093
Bus speed of 600Mhz
No PowerMac G5 has USB 1.1 ports. Unless that is referencing the ones built into the included keyboard.
The best way to find out exactly which model it is, is to get the serial number.
