I've been using an old Lanboy 2 case for years, I just update the MB and CPU. Swapping out parts is really easy IF you have some instruction materials to help out. (I don't need instructs anymore because I'm done it so many times now.) Adding memory, as mentioned by others is easy. Buying pre-built computers is both expensive and frustrating because they become outdated, parts wise, fairly quickly. When my computer becomes slower or new tech comes along I just do the updating myself and save a ton of money, not to mention learning something new.
