Is it possible to use SQL 2005 Express with the CRM 3.0 'fat' client instead of MSDE? I'm tempted to try it but I'm also worried that it might break my install. I haven't seen much mention of it but I've been such a fan of SQL 2005 over SQL 2000 that I'd really love to give it a shot.
I can't seem to find much on the internet about people trying it.
Please drop me a line if you figure it out.
It looks like you can run the server portion of it on SQL 2005 according to this link:

No mention of the client.
