No you CPU is not nearly adequate, but that isn't the biggest problem.
The issue is your I/O bus speed. It is likely to be 32bit 33Mhz, which
is woefully inadequate for gigabit speeds. To obtain anything close to
full duplex gigait you need a 4GB/s bus bandwidth, which means 64bit/66mhz
minimum. Then you would want your SATA drive to be on a separate PCI bus.
Of course then acutally memory speed will start becoming an issue. Designing
a machine that will actually do that at full-speed is not simple and will end
up costing you a fiar bit.
Do you really need it at full speed though?
