I'd think about an i7, but if you can't afford that the i5 should be decent enough. If you don't plan on overclocking, I wouldn't get the K model processor and z97 motherboard. If you do plan to oc I'd invest in an aftermarket cooler. The Cooler Master Hyper 212 Evo is a good cooler for a good price ($30 USD).

It always shocks me at how much computer stuff costs when I look. I die a little inside when I think of what I spent :(
Anyways because you said 3d modeling and animation which is..coincidentally what I do you do want the good stuff whenever possible. I'll just say what I would do different with your build. Take it for what you want.
Personally, I would go with the i7. It won't help you in gaming but come time to make textures in Maya it will. Rendering a scene will set the CPU at 99% for hours so the more power the better. I would go RAID WD drives. Trust me, I lost months of work because of a failed hard drive...don't be an idiot like me. I almost gave up on everything when that happened. I would also consider a 128/256GB boot ssd. It is nice having photoshop and maya open in mere seconds..it just makes the workflow that much better.
Other than that...looks okay. It's a extremely rewarding job and the better computer you have the better work (I feel) we put out.
Oh it is bad. I wanted fairly good colors so I got 3 of the Dell U2414H monitors on big stand. At the time it set me back 1k...but it needed to be done. I have raid setup and everything and it "just works"
Just be sure to keep your data safe. The computer only costs a few grand, your data is invaluable. I can't stress it enough! :p
