Mining query for PC configuration

I want to start mining and I have spare HP dl380 g5 server (Dual-core Intel® Xeon™ 5000 and 5100 series processors with 4MB Level 2 cache for blazing performance; systems support up to 2 processors (2 processors standard on all Performance models)

I am not sure how effective this server would be for mining ?
if not could you please advise what machine should I buy ?

just forget it. to do some profitable mining u need special hardware…
