Multi-format home theatre computer systems are becoming more and more popular in the past few years. While there are many ways to build an HTPC, or modify another device (such as an XBOX or Wii), there are some dedicated companies that are known for their standalone HTPC media products. These include:
The companies offer devices with terabytes of storage, can network to other computers/networks, and are as easy to use as a VCR.
Some of these make for excellent business/corporate display solutions. Some really nice high-end products are available, and at affordable prices. Many of these run from as little as $200 up to $500 for the premium equipment.
