I have owned this PC for a few years now and it is still running perfectly. Since I have included two gigs or RAM extra. When i bought the PC i got it with Microsoft Windows Media Centre Edition which is one of microsofts flagship lines at the time. One problem is the power supply may not be suitable for further upgrades to the system. If you want to include a new high end graphics card you have to install a new PSU which has to be obtained from Dell which will obviously cost more money compared to regular PC part stores. The PC itself can be upgraded easily if there is enough power, another problem is dust which can easily get into the case and cause complete system failures. You probably have to clean it inside out once a year with an air duster to keep it all clean and working.
