Finding specific Segate Drives

[lasergecko]

Can anyone suggest places to get specific Seagate hard drives? For example, with specific part numbers and firmware codes.

Specifically, I'm looking for a Seagate Barracuda 7200.10 500 GB IDE with the following specs:
Model: ST3500830A
P/N: 9BJ036-500
Firmware: 3.AAC
S/N: 9QG0----

Additional specs:
Date code: 072085
Site Code: Thailand

Thanks in advance.
