Heh...I don't know of too many people who know their specs like dividebyzero does. ;-)
Very nice listings. As always, you're not going to please everyone.
Just a few comments. As far as a sound card, I've recently purchased the ASUS Xonar Essence STX card and it is without a doubt, the best sound card I've ever owned. I'm hearing new sounds from songs I've been listening to for decades. And the software customization is incredible. In a nutshell, my computer is now my home stereo system because of that card.
I don't see a need to spend more on the case for the Luxury system. Again, I have the HAF-X case listed and it is as functional a case as you'll find. Has received top-notch reviews from a number of tech websites and looks great to boot. What's the point in paying more for the same (if not less) functionality?
Will also throw in my two bits for the GTX 460-SLI setup. Do the research - it's simply the biggest bang for your buck right now, especially with these cards going on sale for $150 now.
As far as a blu-ray burner, why not? Media files (especially video) aren't getting any smaller and will no doubt get larger as time goes on. At some point in time you're going to need one if you're a big media fan. Completely appropriate for a luxury system.
And lastly, that 30" Dell Ultrasharp U3011 monitor? That's what my tax return is going to this year. I'll let ya'll know how it works when I get it.
