tlowems is right, for what you need, any repack will do and have everything you need right out of the box - and from experience i can tell you that the machine you have will do the trick - you just might want to disable collision detection at the benefit of minimizing the risks of lag (no vmaps - just turn it off in your settings as this requires a lot more processing power - NOTE: enemies will be able to shoot you and run at you THROUGH walls without it though)



However... You are asking about compiling the core direct from source code, and getting the server online from there, am I right? Any particular reason why you want to go that route instead of using a pre-built repack?

Regardless, this is pretty straight forward: http://mmofuse.net/forums/f145/%5Bgu...r-scratch-263/ and has a specific section for the DBC issue you are having... It's simply a matter of downloading a proper DBC extractor, then using it in your wow install directory, and placing the resulting DBC folder in your arcemu folder; where you put your maps. You can grab a DBC Extractor right here: Hotfile.com: One click file hosting: dbc.rar (this will work for up to client version 4.0.1) - here is where I found that link: [REQUEST]: DBC Extractor! - AC Web

Finally, here is where you can get help making it all go public: http://mmofuse.net/forums/f145/%5Brelease%5D-guide-public-server-non-hamichi-100%25-working-3673/
this is an excellent guide that covers just about everything - now if you do decide to use a repack, you may need to go into the SQL Database and manually update the IP of the realm from there as a final step to going LIVE... but IF and when you come to that, we'll all be more than happy to help
