Well, I have the whole thing running on my dining room table, sans the 60 pound cart and the 10 pound batteries. Once the batteries are removed, the power supply is relatively lightweight. Maybe 35 lbs total shipping weight. The two 12v sealed lead acid batteries add about 10 lbs, and, if new and fully charged, will supposedly run the system for 14 hours. The audio, according to what I saw in device manager, is AC'97 based. The video is based on S3. LAN is Realtek. Once I get a HDD hooked up tomorrow, and hopefully install the full Windows XP, I'll submit an update.
