The specs of that system are very low by today's standards. It would struggle running Vista almost certainly and I do not recommend purchasing it. I'll answer the other questions just to curve your curiosity: 1. This desktop has a 64-bit processor. I don't know anything about 64-bit computers. Can I use the software that I have for my 32-bit pc or do I have to re-buy all my programs for 64-bit realmad.gif ? 64bit (or x64) systems can run 32bit (or x86) applications, although there are bugs. There is very little software made for 64bit architectures at the moment, but that will change. I do recommend purchasing a 64bit system if you're in the market, they will overtake 32bit in the next year or so. 2. I see that it come with linux. Will these run windows? I would like to run vista home basic or vista home premium with the aero theme (after upgrades of course), but If I can't run vista I would at least like to run xp pro. This system won't run Vista (or at least usably.) It would run XP Professional on the other hand, but even then a lot of your applications are going to be sluggish. 3. I want to put my internal dvd burner in this desktop. Is that possible? No, there is no expansion bay on this model. 4. Is it worth it? I would mainly use this pc for fun, but I will use it for work as well. Not in my opinion, there are some good deals out there, but this isn't one of them. If you wouldn't mind posting your price range I can help you in your search.
