Thanks for the quick answer. So now I have more questions.
Motherboard--loses the second PCI2x16 slot so no second video card, right? I suppose I can count on buying 2x the card for 1/2 the price in 2 years anyway?
RAM - 4gB, check. No problem with DDR2 800 slowing down this system?
Case - Are two fans really enough? Heat is the enemy.
PSU - I'm maxing a 450W power supply with less system, I think I like the overkill. Of course, if no second card, I can probably back down some.
HDD - Good call. I sometimes get Seagate blindness.
ODD - It's not so much on the fly as doing so much reading & burning, I like to split it up to lower the duty cycle and give 'em a chance to cool. I've got Lite-on blindness, too.
Video - Thanks for getting me in the neighborhood on the Radeon GPU numbers.
