Where is the actual problem then? Taking out the switch works (although not really practical as I need the shuttle for downloading over night), and the switch seems fine with the shuttle PC.
All part of troubleshooting
If you take the Shuttle PC out of the switch and put the main PC into that port, does it work?
Does it work in
any port on the switch if it is the only machine connected to it?
What you can do is get hold of Ethereal and WinPcap and capture network traffic on the main PC when it is connected to the switch, to see if it gets any response at all to the DHCP queries.

Did you try the ping and ARP tests from before, when you assigned IP settings manually?
That should also show if you are able to get even layer 2 information correctly through the switch.
