ML350p as a computing server

Hi,

For our lab, I want to get a central processing server for our long-running data analysis tasks. I am considering getting a basic ML350p gen8 server and adding some components to get a high-end system:

ML350p gen8 server (669045-425, comes with a single E5-2609)

Additional fan (659486-B21)

2 x boxe E5-2680v2 (BX80635E52680V2)

4 x 16 GB memory (ECC)

I'm not asking for any guarantees that it'll work, but am I missing anything obvious here? (For example, do I need more than the additional fan to be able to run the second CPU?)

Thanks for any advice!
