Similarly, the Atom meets the basic computing requirements of average users but not much more. This means you can check email, browse the web, use Office but can’t utilize advanced HD video, 3D games, and so forth.

An exceptional use for the Atom platform is a home server due to fantastic performance per watt. It uses around 2 watts of power under load, whereas a common processor such as the Core 2 Duo uses 60W+. As energy costs go up, the total cost of ownership of a server is skyrocketing. So while the intial cost of a server or desktop suitable for running as a server may be low ($500 on a budget), at 24/7 the energy cost will be $100-$400/yr. In contrast, a 24/7 Atom-based server would cost approximately $10-20/yr. Substantial savings.

There are some great uses for Atom home servers:

1. BitTorrent. Dedicated 24/7 upload and download without worrying about utility bills.
2. Home automation. You can leave a home-automation management server running 24/7/365 for probably under $7/yr in energy.
3. Centralized storage. You can make your own NAS – most efficient in conjunction with the above services.
4. Music server. Always-on access to locally-stored and Internet music.

Using the Atom platform for a home media server is possible, but only with streaming lower quality video. HD quality isn’t going to work.

TranquilPC offers an Atom-based D945GCLF motherboard for about $100US. Throw RAM, flash-based storage, power supply, and a case on top of that and you’re looking at about $200-$300 total. TranquilPC and other vendors are starting to offer pre-built systems as well, but generally run $500 and up.

Anyone have other ideas for the Atom platform? Inexpensive solar-powered server or desktop, maybe?
