my 2 cents.
I would fill up that case with fans of your choice! (it boasts up to 10 fans) personally I get all my fans from SVC.com I <3 my yate loons!
depending on how big you want your SSD, you could get the 128gb crucial m4. Or if youre uber badass, you can just get 2 of the 64's and put them in RAID0!
btw the 2 500GB WD's are for RAID0
the xonar dx is definitely your best bet since it's PCI-E x1 and it will fit into your motherboard ABOVE your graphics cards so it wont be in between blocking air movement leaving your gpu's cool! im personally going to be getting that sound card sooner or later to replace my audigy 2.
If you end up getting 2000 in reparations, a worthy upgrade would be upgrading your gpus to GTX 570s, or if patience is one of your virtues, you can wait 'til the new 28nm gpus come out and SLI/CFX (depending on which company you go with) those!
good luck buddy!Edited by revamper - 7/19/11 at 8:34pm
