2x580s would be very hardpressed to actually use the majority of their power for any games in the next year (it's hard to say past that about any gpu config). If you really want to use those 580s, then you should probably consider using 2-3 monitors or doing 3D gaming, cause a pair of 580s should be able to play almost every modern game on max settings across 3 1080p monitors. At 1080p by itself, however, I don't think you'll even max out a pair of GTX570s on almost any modern game @ max settings (the exceptions might be Crysis or Metro 2033 with all their effects enabled). If you've got the room, you should get a pair of 570s and 2 more monitors or a home theater speaker system for 5.1/7.1 If you actually have the $2500 and you want to spend all of that on this system, you can do a few better things here.
First, I'd recommend against the SSD. This doesn't help gaming nor multimedia. It just does things like, make your programs start a bit snappier and start up your system faster. Replace this with a Spinpoint F3. I don't know how much storage space you currently need to hold everything you've got, but you should get just that much with maybe 1TB more, in 2TB drives or 1.5TB drives, whatevers better on sale that you can get to your target size, performance isn't particularly a big issue here, as long as its new and has a large capacity, it's probably fast enough as an internal hard drive. Personally i've got 2.25TB of videos, 945GB of music, and 192GB of games, take it from me that just going with internal hard drives that are cheap are both fairly good enough, and the easiest thing to add on later if you find you'll need more space. You should probably only need either a spinpoint F3, maybe another 1.5-2TB HDD if you're already cramped for space, otherwise save it for later. This should take you from $465 of storage down to $60~$130 netting you the ability to keep those 580s AND give yourself a hefty visual or sound upgrade.
I'm also going to have to criticize the choice of coolers here. When helping my roomate build his most recent machine, he went with the 212, and that is easily enough to put on a heavy overclock of your CPU, that should save you another $50.
Your RAM looks ok, and i'm not going to look at that mobo. PSU's probably not a bad choice.
Why that monitor? It doesn't look appreciably better than the 24" asus monitor I bought years ago for more than $100 less. If you're going to pay that kind of money for a monitor it'd better be IPS (much much better color than the vast majority of monitors available) or 3D (if you're into that). If you'd prefer supreme quality, go with an IPS monitor for a similar price to that one, or go for a 3D monitor if that floats your boat (would let you flex your 580s' muscles a bit more), or if neither of these sound particularly appealing (you don't care about 3D and you've always found normal monitors to be fine on color), then just drop down to the $200 range 24" monitors and get like 3 if your desk can fit them. That'd let you get the best out of your dual 580s.
If you don't have room for multimonitor setups, go for a larger monitor with a higher resolution. If you still don't have room for that, then go for a real audio system (Receiver/Amp + home theater speakers + subwoofer). This will add a serrious degree of awesome to your movies + games, especially if you get a 5.1 or 7.1 system. However, these options will cost a few hundred dollars, so only do this if you end up with only a single 1080p monitor and a pair of 570s instead. As far as multimedia goes while still packing an absurd gaming punch, that's probably the best you can do on that budget, Movies w/o a good sound setup are a lot worse.
tl;dr: given your priorities, I'd go with a cheaper monitor or an IPS monitor, drop down to a pair of GTX570s, take the HDD recommendations I made, down the heatsink, and buy yourself a nice $800 Home theater audio system. This will give you a ridiculously good media enjoying environment while still being able to play any modern game on either high or max settings at good framerates for the next foreseeable future.
If you don't wanna go the audio route, I'd take the HDD changes, and the heatsink change, get a cheaper monitor and get two of them and put them next to your current one (or just get 3 new ones if you don't have the current one anymore)
