The 160 gig drive is Ultra ATA 133 (need to upgrade your motherboard or use an adapter card) and is $105.

I don't use flat screen monitors, since they are so overpriced and I see the flicker. My dual 19" monitors at home run at 115 Hz (refresh rate). Check CompUSA this weekend and also Best Buy. Recommend 19" tube instead of flat screen LCD. Good price point between cheapie 17" and overpriced 21".

Shipping on monitors gets expensive, not for the weight, but for the insurance. Becky may be able to respond as to UPS treatment of shipped items.

You're processor is pretty fast. Upgrade the processor, motherboard, and memory (faster kind) at the same time. You can reuse the hard drive, cd-rom, case, etc.
