Those older AMD chipset boards are solid are not they? I installed a dual Opteron 242 box with 2GB of RAM (4x512MB) using the 2881 board I was talking about. This was about two years ago. A 3ware 7508 + 6 200GB IDE disks + 2 scsi disks as the system disks + 350 watt redundant, ATX sized, 2themax power supply :D. I never got a complaint about its stability. Another Tyan box that is relatively new that (Tyan 2865) I built (but running Windows XP 64-bit) has also been rock solid once I replaced the incredibly expensive and incredibly unstable 3dlabs Wildcat Realizm 500 with an elcheapo ATI card. If I had known that 3dlabs was leaving the market... So if Tyan is losing its edge with its new stuff...that is a real pity.
