Server Build Parts Check
 

I am finally decided on how i am going to be building my server now i am just a little sketchy on what parts i should pick up. I am going to be running flexraid so i will be able to use the onboard sata 2/3 controllers without the need of spending a lot of money on raid cards and have a decent amount of hard drives right now.
