I've priced the ST373453LC, and it's 67% more than the ST373207LC ($311 vs. $519 at newegg, for example). These new Supermicro X6DHR-8G 800MHz FSB systems seem to be working OK (even under load) when running a kernel with SMP enabled. I offered my configuration in case jhb or someone else would be interested in what seems to be an interrupt routing problem.
