Total $1008. All prices are from newegg and doesn't include tax/shipping/handling. Believe the speakers are a limited time offer. I was going to add 1GB memory, but not within your budget. SO only 512MB. You might want to look at alternatives such as the emachines t6522 which has amd athlon 64 3500+, 1GB DDR PC3200, 200GB hard drive, DVD+_RW DL Burner, WIndows MCE, and tv-tuner. Or HP a1130n which has the same specs, but a larger SATA hard drive, 250GB, and an additional DVD-ROM, but no tv-tuner. Both are on sale at circuitcity. For around $700, with CRT, or lcd. OH ya, it has a pci-express slot, so just buy a 6600gt and you have a gaming machine within your budget.
