Is Poweredge T30 strong enough for the task or should we go for the T130

As the title states, is the poweredge T30 good enough for a small city as we are looking for the cheaper option or do you think it would cause problems in the long run, i also saw on a post from a while ago that someone said it would work on a vps with dualcore and 2GH processor and 8 ram but we would buy it with 32 just in case, thanks for your time :).
