Low end GE Force graphics card
couple of 500 Gb HDD from Western and Seagate and an external 750 Gb from Western

Have been completely on HTPC for the last 3 years, routing my once dedicated multichannel system to it. Now using just two channels and a sub. This setup was from my 2nd upgrade last year with just a recent upgrade to one of the monitors. Have not bought a single CD or DVD since, all HD movies and music from online sources
