Hi guys, I'm in the market to build a home server. I've been using my high-power, dual-processor xeon machine to download rather large files (both over bittorrent and downloading large analysis files from work) and to essentially act like an FTP/Media/HTTP server to make my media and documents available over the local network at home and over the internet. I've been having to leave this thing on a couple of nights and besides causing a mini-brownout whenever I turn the thing on, my electric bill is starting to get out of hand... I'm looking to build a (somewhat) lower power machine that I can stick next to the router and leave it always on to manage my downloads and act as a file/media server. Right now I'm trying to figure out the best CPU (since I don't really want to spend a lot on this build). I was looking at potentially an i3 but I'm thinking that may be overkill for what I want to do. I was also looking at the pentium and the atom, but I don't really have any experience with either of those processors to know what to expect in terms of performance. My main requirements for the motherboard is that it has gigabit LAN and it has the built-in Intel RAID (rapid storage manager). I use the built-in LSI SAS RAID for the system disk and the Intel RAID for my documents and have been very happy with the performance of both of those (I've tried some cheaper RAID cards in the past, like $50 or $60 from fry's, and they gave me nothing but grief). It also may be nice to have a few PCI slots to support potentially throwing in a few higher quality RAID controllers in the future. Everything else I'm not too picky about.
