total=620.95 a little over but is pretty decent. you can cut the ds3 to the s3 to save a little. the memory is damn good but it is the looser timings because of the price. you can always upgrade with another gig later. oem winows xp home edition. keyboard mouse and speakers arent the best...but personally im not one to care too much about the mouse and keyboard, but you can always cut to the s3 and get better input devices. dont think im missing anything else...just kinda threw it together but it looks decent
