There's been quite a few pre-packaged media servers popping up lately. One of those that looks promising is the Savicon Entegrator. According to Savicon's website:

All of our products include the exciting and simple to use E-Pad. The E-Pad puts you in control of your digital Media. The main components of the system are shown here. On top is the E-Pad. The box the E-Pad is resting on is our high performance A/V controller. The E-Pad communicates with the controller and other devices via the wireless 802.11b WiFi standard for computer networks. By adhering to standards, we are able to bring you products that are high performance and reasonable cost. Sticking to technology standards also provides a clear upgrade path as technology advances.

Some basic specs of the Entegrator Reference System are:

There are several configurations available and the specs are for the low-end system. According to Mavicon.com, a complete system ranges from $9900-$14000, depending on the configuration. I really doubt it that Savicon can compete with that price point but I've been wrong before.
