My server specs are P4 3.0GHZ 2MB Cache 64BIT HT, 2GB of DDR 400 ram , two 80GB SATA 150 Western Digital hard drives, running hardware Raid 1 (3ware Raid card), 250GB SATA 150 Western Digital backup hard drive.
So far I am just running two forums on the server. But next month I am going to be launching a high bandwidth website. It should really stress the server. Then I will be able to see what this server is made of.
