1. Don't buy ram from Apple buy it from a number of different vendors.
2. You don't have to buy a monitor from Apple.
Even though the quality of that monitor is probably better than you are getting from Dell. All of Apple's monitors are excellent as far as quality goes...even the low end. They are also price competitive with QUALITY flat panel monitors from other vendors.

When you talk about high end go price those computers with duel Xeon processors or Duel AMD 64s. Duel 900 & 1Ghz sytem busses. That's right each processor has a 900Mhz or 1Ghz system bus. Windows XP Pro. That is what you can compare Apple Duel G5's with.
