further to rsharich's very informative answer regarding the logic board version, a little diversion...
It seems you can also verify the logic board version without opening the device, by entering the special diagnostic mode that exists on these 5th gen iPod (and other iPods). here's how:
1) reset the iPod 5th by pressing and holding the Menu and Select(center) buttons for a few seconds
2) when the Apple logo appears, press and hold the Select(center) and Previous(left) buttons. This should cause the iPod to beep and display a white screen with the heading "SRV Diag Boot"
3) now press Menu to enter Manual Test mode. you'll then see a menu of available tests
4) use the scroll wheel, or press the Next(right) button to navigate to the "SysCfg" entry in the menu
5) press the Select(center) button to select the SysCfg entry. you'll see several lines displayed on the screen, the 3rd line down is the logic board version
for example, I know my 5th Gen iPod is an original vintage one with 30GB hard drive. the 3rd line in the SysCfg page for my iPod says "8201763A" == 820-1763A logic board version
