It sports two very silent 120mm fans, has a removable mobo tray... This one is undoubtedly the best one I ever had (having owned a plethora of Antecs and Chieftecs)...
As for the PSU, any high-end offering from companies like Antec (PSU-wise they are just great), Enermax, PC Power and Cooling, Seasonic will not let/power you and your SLI rig down... Antecs are actually very affordable in comparison to the other ones... The TruePower 2.0 TrueControl II 550W can be had for
$ 109.99, which is a bargain, considering its massive power...
About the rest of your setup... I suspect you're willing to overclock, or not really...? If so, the Fatal1ty SLI board is about the best there is (next to DFI's LanParty nF4 SLI or maybe even EPoX's EP-9NPA+ SLI), if not, the Asus will do just fine...
Although I'm not a fan of it, the dual 7800GTs will do great... Make sure you pick the eVGA ones, because those have a lifetime warranty, and can be upgraded through eVGA's step-up program...
The hard disk is a matter of which-one's-cheapest, because both manufacturers are very good, maybe a slight nod to Seagate for a more silent operation...
Like
HardWarrior stated before, I would invest in a decent sound card for your comp... It will clearly make a difference... Creative SB Audigy2's don't cost that much anymore, so I'd consider one of those...
There are some very good alternatives for your RAM... OCZ, Corsair and G.SKILL Extreme memory sets of 2GB can be had for around $ 210 on Newegg (after Mail-In Rebates), so I would take one of those...
