Here's a sampling of what is going into the project tivo:
Maxtor 120Gb hard drive
Weaknees TwinBreeze Complete upgrade kit with a PowerTrip
Linksys WUSB11 Wireless-B USB Network Adapter
Window kit + EL cable
This will yeild a 160hr TiVo for about the suggested retail cost of a 80Gb TiVo. It will be quieter than a standard TiVo, use less power, and look better in the process.
