The Dell Dimension 9150 is an excellent computer that is really worth its money! It comes with a 3.2 GHz processor that is excellent for handling even the hardest of tasks, tasks that require high processing speeds to work well and smoothly, and barely challenge the processor's mighty speed.
The 1GB RAM is a bit of a downside to the computer as it really doesn't help the computer when running programs that consume a lot of the available RAM, and this can really limit the capabilities of the machine, although most retailers that I have come across offer the computer with 2 GB of RAM with a maximum of 4 GB as an upgrade compatible with the computer.
The huge 160 GB storage space per hard drive disk of the two hard drive disks means that there is ample space for many many files ranging from media files such as thousands of music and video files, to hundreds to program files that you may find necessary or want. The graphics card is a G-Force 7800 GTX graphics card that is decent for gaming, and undoubtedly above the sub-standard graphics cards issued in many machines around the world, old and new.
The CPU is actually quite large compared to others I have seen although I don't find it an issue because it's placed beneath my desk on the side, not really affecting my work space, and only occupying a small amount of my leg room.
Finally, the TV tuner card in the computer allows for the computer to be attached to a TV (LCD TV's only I believe) meaning that the size of your screen can possibly reach up to 60" if you have the money to afford an LCD TV that is 60" wide, and the other benefit of having a TV tuner card means that the computer can be used in a variety of places, and the fact that it can be linked up to a television means that you don't really have to spend extra money on buying a separate monitor.
