Hi Steven, There are a couple of threads that discuss this very question. I think when we came up with this spec we were being very generous. As you can see from the threads below, only 1GB of memory is needed for a running system (loading the data is another story). As for as disk space requirements go, 10GB was allowing for significant headroom.
