I think some people on this site are getting ahead of themselves with their recommendations. $3000 is a very high budget for a personal computer, and I think it excites people into recommending some parts that won't bring you the most noticeable difference in performance for your money. Even with a budget of $3000, it is important to keep in mind that your money will not stretch to include all that is out there, and that decisions must still be made about what parts will make the biggest difference for your experience-and at the end of the day, isn't your experience what really matters? $3000 is enough to buy a rocking PC, just make sure you don't spend it on eccentric flair that you will be hard pressed to notice when it comes down to actually using you computer.
With that in mind, I have a couple suggestions to steer you in your search:
1. Go with Haswell over Ivy Bridge-E. Haswell uses a newer architecture, and also happens to be cheaper for both processors and motherboards. Most applications you will use on a day to day basis (photo-editing, games, web-browsing, email) will take advantage of Haswell's more efficient architecture and run faster than they would on an i7 4930K. When you buy an i7 4930K or similar Ivy Bridge-E processor, you are paying extra for features like 40 PCI-E lanes that you won't be able to take advantage of. Don't take my word for it, look at this Anandtech comparison:

2. Don't get 2 SSDs. First of all, they won't provide much additional performance in RAID. RAID0 was a great option when VelociRaptor drives were the fastest available hard storage for consumers, but SSDs have completely changed the game. Don't believe me? Believe these guys:

Get a single SSD. Get a really good SSD with an enormous amount of space and don't look back. I personally use a Samsung EVO with 500GB of space, and I think it's the best $280 (I got a great deal) I've ever spent on my computer. With your budget, you could easily go with a 1TB drive and keep all your games, music and movies on it. It might sound excessive, but when you account for the noticeable difference in load/copy times, it won't seem nearly as excessive as a 4930K processor. With a 1TB drive, you can create 2 generous partitions for Windows/Linux and avoid the complexity of adding another drive (also keep in mind that larger SSDs are faster than smaller ones for technical reasons that I won't get into here).
3. Don't get a sound card. Don't get a network card. Any motherboard worth buying will have a perfectly capable network adapter (and probably two of them). Network cards are a stop-gap solution for older computers and an important tool for servers. Get a motherboard with an Intel NIC and Wireless AC and don't look back.
As for sound cards, motherboards generally have that down as well. While sound cards do provide features and occasionally quality that isn't available on all motherboards, they are rarely the best option. If you have high quality headphones or a good sound system, consider buying an external sound card/DAC. I bought a $200 Essence STX card, and it was the single worst buy I've ever made.
4. Lastly but most importantly, your monitor is what you will spend your day looking at. If you have extra slack in your budget, place that slack here. What you buy here should be based on personal preference. Go to Best Buy or Fry's and try a couple different set-ups out. You could go with 3 1080p monitors in Eyefinity or Surround or you could go with 1 4K monitor. Different people are looking for different things, so make sure you know you'll like it before you invest a thousand bucks in your setup. While I'm on this point, I will also mention that you should make sure you have the graphics horsepower to deal with whatever you choose and then some. Games will only get more complicated, so this is an area where a little future proofing might go a long way.
It would be unfair to leave you with all this advice and no concrete suggestion so here it goes:
Tower: Corsair 550D, will fit everything with room to spare - $150
Sound Card: No. $0
Video Card: Geforce GTX 780 - $550
Router: Not sure. Let's say $200
Processor: i7 4770K. $339
Motherboard: If you must have wireless, go for the MSI MPower Max. If you can leave that feature off, the Gigabyte UD5H would be my choice. Neither are particularly flashy, but they are from solid companies and will do everything you want them to do. Don't get roped into buying a $500 motherboard with features for people that want to use liquid nitrogen. $220
Heatsink: Corsair H100. Will cool your processor, and it's super low maintenance. Even if the thing leaks (which they don't), you'll get just non-conductive goo all over your computer and save yourself the hassle of buying another $3000 computer. $110
Memory: RipjawsZ DDR3-2133 9-11-10 4x4 GB $130
Cooling Components: In heatsink. $0
Blu-Ray Burner: Ask someone else, I think they're outdated unless you are one of the 5 people on earth that has a Blu-Ray collection. Don't forget to get software for it. $50
Printer: Not sure. I only use a laser printer, and you'd probably want ink. Say $150
Web Cam: $30
Microphone: $15
Network Card: No. $0
You've left out
Monitor: If you read those huge blocks of text above, you will know that I don't suggest you get anything before trying it out first. Say $500
SSD: Samsung EVO 1TB $600
Power supply: Seasonic 650 watt Gold $100
Keyboard/Mouse: $100 should get both of these. I love G400 mice, but they break and I don't recommend them to others. I use hand-me-down keyboards because I like old Dells.
That brings you to a total of $3244. A little over-budget, but you've suggested that might be okay. If you want to cut back, and must have an expensive router/a printer/a Blu-Ray burner, I'd suggest going with a 4670K processor for $100 less. If you don't think you can fill up a 1TB SSD in the next 4-6 years, go with a 500GB for $300 less. You can save $50 by going with less memory (8GB is fine if you don't use virtual machines).
That's all I have to say.
