Here's my critiques. This is based off of you mainly wanting to game, since of your comment about SLI in the future.
1) Don't ever buy an i7 for a gaming rig. The ONLY difference between that CPU and an i5-4670k is 2MB of L3 cashe, hyperthreading, and $100 in your pocket. Having an 8MB L3 cashe over a 6MB one makes zero difference for gaming. Hyperthreading only gives you 4 "virtual" cores that are only about 30% as effective as a physical core... AND it only applies to double-precision workloads (i.e. calculations that have to be accurate out to some hundredth decimal place)... and since games don't do more than a tiny handful of those calculations, hyperthreading gives pretty much zero benefit... and that's not going to change any time soon.
2) Good pick on the motherboard, especially for a budgetish rig.
3) Bad pick on the RAM. It's overpriced, it's a bad brand... and there's too much of it. 8GB is enough to simultaneously run battlefield 3, photoshop, AND 30 tabs in chrome.
4) Good pick on the SSD - by far the best choice out there. You know that a lot of games don't get any benefit from being on an SSD, right? Only put on there the ones that have loading screens you want to get rid of, like MMOs or skyrim. (If you load first into a match of CoD, say, you just have to wait there for the other players to load, so there's no point.)
5) I tend to find that Barracudas run a little hotter and noisier than Caviar Blue or Blacks. That's a pretty good price, but if noise is a thing for you, consider switching to a pair of Blues or a Black.
6) Try to get the video card up as much as you can. You really, REALLY don't want to use 3-way SLI. The second card you add into the setup increases the performance of a SLI setup by about 60%... the third card only increases it by about 20%. Not really worth the money. A single 770 will run games on the ultra preset at 1080p, and is EASILY obtainable with the $100 you didn't waste on buying an i7. You can either get a 770 and get a second one later, or get a 780 and be set for a good long time.
7) Don't bother with a sound card. While that is starting to get to the point where it's better than the onboard sound, you're going to have to have either audiophile headphones or a rather expensive stereo setup to make it worth the money. If you do have that, great! (And PM me, because I have a Xonar DX that I bought and ended up not using in my HTPC because I went with a TV tuner card instead.)
8) Great pick on the case, that's a wonderful one.
9) Your power supply... well, if you were doing tri-SLI, it a decent option, but for $170? You can get a 850w Seasonic for about $90-$110, which will be enough for 770 SLIs.
10) Ditch the blu-ray reader. The trouble is that you have to pay for it, and THEN you have to pay in order to get the software that's licensed to read the DRM-infested blu-rays. Compare that to the half-dozen different ways of getting free or cheap 1080p content, and it starts to look like a fairly bad idea.
11) "Gaming" keyboards are rip-offs. You're paying for the lights and for "macro keys." Either just get a cheap membrane keyboard (which that is a membrane keyboard, and at least not $60), or pony up and get a mechanical keyboard and learn what it feels like to type on a cloud of boobs.
12) I don't like buying mice online very much - if you know you like that one, great, but preference in mice is such a finicky thing... it took me probably 120 mice before I found a good replacement for my old Intellimouse Explorer 3.0.
13) Don't go with windows 7. Buy windows 8.1 x64. The reasons for that are many, but if you take five minutes to change settings and uninstall the godawful metro apps, it's just windows 7 with many things vastly improved... and the biggest thing is that windows 7 OEM is locked to your motherboard and processor - windows 8 OEM can be deactivated and moved to a new computer when you upgrade.
That's just my advice - you have some good picks, and some picks that aren't a good use of your money.
