Your car would also overheat if you removed the shroud around the fan
behind the radiator. Most computers rely on the case for decent airflow.
Your lockups may be caused by overheating, so if the case is still off
the machine, that's the first thing to do. Second would be to make sure
that with the case on you're not still overheating.

Sounds like an interrupt storm. Try the other onboard transceiver or
plug another ethernet card in. Move cards around in slots or play with
the BIOS to juggle interrupts.

How busy is the network segment it's plugged into? Reliable switch/hub?
