Which of these two dedis would you keep?

I have two dedicated servers, but I am only using one. Invoices are due soon for both and I need to decide which one to keep. What would you do?

Server 1: HP BL460C Dual X5150, 16GB, 500GB I am not really using all the RAM, although that may change.

Server 2: Intel Core2 Quad Q9550 2.83GHz, 8GB, 1TB I am not using most of the HDD.

They are both the same price.
