This build is $5 over budget. You can drop down to a slightly smaller HDD to get it under budget if you must. Please note that it DOES NOT include a DVD/Optical drive as you can likely recycle that from your existing machine. It DOES include a 19" LCD monitor so you do not have to squint =) . The components have overclocking potential, if you get the urge, and the video card, while not latest tech, will drive this monitor to all but the highest settings on current games.
