It has a Dual Core AMD Athlon II NEO N36L 1.3GHz CPU.
I have been using Ubuntu Desktop for the last four years, but have not done much on a production server, so these are exciting times

Question: Which version of Fedora 14 and Amahi should I install, 32-bit or 64-bit?
If possible, I would install x64-bitness to do the system justice, however, would I miss out on certain apps or are they all supported under both architectures?
Anything else that is different between 32-bit and 64-bit installations that I should consider?
I intend to use the server for file serving, backups of Mac and Linux computers, home networking, music and possibly video streaming.
With that in mind, should I get myself more memory than the 1GB I currently have or should it be enough for now?
Some feedback: While I understand the reasoning behind it, I find it inconvenient not to be able to use USB for installation. Isn't this the way to go in the future? The server I bought does not even have a DVD drive as standard. Not a whinge, I just hope you guys are working on this, otherwise I hope you will

Thanks a bunch!
