Hello, I am new to mining also (near a week), and have absolutely no experience in CPU mining 
You may test the hash-rates of your server in sha-256 and scrypt (for Litecoin and others)
using some multi-threaded miner, such as cpuminer ( http://sourceforge.net/projects/cpuminer/files/ , http://github.com/pooler/cpuminer ),
and make calculations based on this test.
Its more likely that sha-256 mining will not be profitable, but scrypt mining may be.
This answers may be helpful also: http://bitcoin.stackexchange.com/questions/9637/fastest-cpu-miner
But anyway I am not experienced in CPU mining
