So I'm thinking about upgrading to a new computer. But before I do that, I'm wondering if my Dell XPS 630 can be upgraded at all? E.g., can the motherboard be changed for a new one? That is pretty much all I'm wondering at this point, because if that's the case then I can upgrade everything else without a hassle. I've just heard that Dell equipment is a pain to upgrade due to its proprietary parts and restrictions. Is upgrading this machine possible? The current MoBo is a Druid a00 i believe.
