For a very good price and a very sound build I would certainly consider DELL, the downside they can be slightly more awkward or expensive to change some parts as some items none standard. If you are not likely to want to do any mods then this should not bother you. You really need to decide waht you will use it for, if for instance you are likely to save loads of photos then disk storage size should be considered. With a desktop PC you may consider two seperate drives for security. other considerations would be the software installed.
