If you have a Server @ Home or Work, did you prefer to build it yourself or buy it from a company such as Dell.
Definitely prefer to build myself. I built my home server with parts bought from newegg: - Gigabyte GA-X58-USB3 - Intel Core i7-950 quad core 3.06GHz - 24GB of G.SKILL Ripjaws DDR3 1333 - Adaptec 1430SA HostRAID (got this on ebay, works better than Intel Matrix RAID) - 2x WD2500YD and 2x WD1001FALS At work, I'll typically build something based on a SuperMicro rack server.
For work I think it's better to buy it from a company. I would built it if it was for home using an AMD Fusion APU, it's perfect for home, besides, you can turn it into your home media player also
i built my own whs for home use. using an athlon 2 dual core, 2 gb ram, 1 tb. drive with a second drive to back it up. using whs 2011 rc until the rtm comes out.
