I am trying to upgrade a PowerEdge 2600 server I have which I use for my personal training server. It is a very nice server, in great shape. But it is dated now with a 32bit Motherboard. I am wondering if anyone had found a 64bit board that will fit. It does not have to be a server board and I would prefer that it is not do to the cost. I am about to build a new server for virtualization testing, study and so forth and really would like to use this box, it is rock solid with good air flow. I can't tell just how proprietary this case it in terms of taking a standard ATX MOBO or not. Cases are not that expensive but again I like this rock solid server and hate to toss it.
