Gibdo, somehow I had the sneaking suspicion that I could buy all the parts in your computer seperately for less than the price you paid...
As a way of testing that theory, I checked a Canadian retailer that I knew had a custom system option on their site, and I configured a more or less
equivalent computer. It's missing a printer, but it comes to about $820 Canadian after tax. A printer could be had for about $40, bringing it up to about $860, which is around $575 US. Considering that I am sure that Compaq assembled their PC from parts built by the lowest bidder, and got deals on quantity... meaning that they got a FINE commission on the computer they made you.
That being said, I think that once you upgrade your memory, your computer will be serviceable, but it won't be anything to brag about to your friends.

And most certainly do NOT tell them how much it cost you.
