I purchased everything at Frys, also know as the best store EVER! They always have killer deals, especially on the weekends. I chose an ASUS M2N-E motherboard with an NVIDA chipset because it has on-board RAID controllers. I've also heard a lot of good things about ASUS. I can support up to a six disk RAID array (0, 1, 0+1, 5, and JBOD) . I also purchased two 500GB SATA hard drives which were insanely cheap. I don't have a true terabyte of storage because of my RAID1 setup, but still 500GB is a lot of storage space.
I went with an AMD Athlon X2 5600+ dual-core processor along with 2GB of RAM. I can support up to 8GB of RAM (DDR2 800) but with only 2GB this thing is still smokin' ! I'm sure most everyone doesn't care or is asleep by now, but I know Rick can appreciate this tech talk. :)
Needless to say, I'm very happy with my new rig!
