I removed the MB in mine, since I was getting the INT-2 hack done as well. It is easier to get the battery replaced with the mobo out, but I think it is not necessary.
Congrats on getting your 3000 resurrected, I just finished putting my CSPPC one back together last week :-)
*edit* and doing the battery in the 3000UX once I get the next replacement from Red...
