PC parts were as expensive as hell in general back in the olden day.
You had to spend $200-$300 for some good parts. Nowadays, you can get a fast processor for $150 and a good HD for also $150.
*Educated guesses here, I'm young.
Anyway, the most I spent was just recently on the Dell 20% deal. $430 for the Sony G420S 19" monitor. Ooooohhhh baby, I can't WAIT until I get it!
