Query: Machine Running Strong After 3+ Years

I've had my Dell 8400 since 2004, and I have zero complaints. As someone who is technically inclined when it comes to computers, I have maintained this machine well. The one time where I needed to call Dell's customer service, I received prompt attention to my problem (even from India) and had a replacement memory module shipped to me within 3 days. All of it painless. I would suggest this PC to anyone that was asking - even if Dell no longer makes this particular model.
