Hi! Due to a very tight budget, we're considering buying what we call 'old technology' nodes ... ie mobos and CPUs that are based on technology that is being replaced but that can still be found for purchase. The obvious idea is that we can add more nodes (slower but cheaper), instead of less (but faster) nodes. We're evaluating building AMD socket A or Pentium socket 478 machines. Do you have any recommendation on particular motherboards? Any particular chipset that should be avoided (badly supported) in Linux? I've heard good things about MSI and Tyan mobos, but haven't had any personal experience with them. I've been bitten in the past by a bad mobo design and would not like to be bitten again. We will be buying standard ATX mothers and building the nodes ourselves.
