I am going to wait a few days before pushing the buy button but I would appreciate advice on this selection of components. 
I need to keep it under $1000 but if there are any things I have left out (ie do processors usually come with paste or do I need to buy separately?)
Thanks very much,
Randy

The link you provided merely goes to NewEgg's log-in screen for existing customers... and, NO, I don't want your ID and password! Maybe you should just copy and paste the info into the next forum post so we can comment on it.
As for the one question I can answer, I have never had thermal paste supplied with a CPU. I have always had to buy it seperately.

Sorry about that : 
EDIT: please see below for clearer image (without prices)  

That seems a little hard to read so here's one without prices

The Asus board and the Ivy Bridge i7 should be a good combination (unless there is something I am not aware of).
The mid-tower case is a nice unit and should give you enough room to work with it.
Glad to see you went for a hefty power supply... that's always a good idea (I hope it is also rather quiet).
The 2x8GB of Corsair should be plenty of memory (do these sticks come with built-on heat sinks?).
My only concern is the single SSD hard drive; can I assume you will transfer at least one (hopefully 2) existing drives to store audio and synths/samples?

According to this they have a heat spreader...would that suffice. I wonder if I should add a fan...the case seems to have 3 places for one.

Yessir, I have an abundance of storage drives...my only concern is the C drive (the new 128 GB SSD) won't be quite big enough even though my current (dedicated) system is only using 100 GB.
Thanks very much,
Randy

Yes, the heat spreaders will be fine for the RAM. As for fans, you will need some means of heat transfer, but - as you know - the more fans, the more noise. If you can isolate the system to prevent its noise from becoming a problem (during open mic work, etc), a CPU fan and one case fan (to draw hot air out) should suffice. Obviously, the quieter the fans, the better. If you can afford two (or even three) ultra-quiet case fans, great! It means you have deeper pockets than I do.

You're right to be concerned about the small SSD drive; after installing the OS, Sonar (and all other program files) and anything else that doesn't belong on the storage drives with your audio and other stuff, you will have no room for expansion. I don't know if SSD drives suffer from the same malady, since they don't have moving parts to wear out, but any hard DISC drive starts showing signs of "indigestion" once you get past 50% capacity. SSD drives are great for a lot of things; I just don't know how much I would trust one in a dedicated DAW system. It's your call.

Thanks, I'll add a case fan

I've heard this isn't the case with SSD but I don't know....perhaps I should go with a larger C drive...maybe I should go with a fast HDD...any suggestions there?
Thanks again,
Randy

randy,have you ever built one before?
its really not that hard,but there are something to look out for and something to consider,the two i use now for x1 i built
yes silent fans with shock mounts,not screws.
case needs be one of a kind to keep the sound of noises inside,not out.
power supply needs to be silent,if you need any help send me a pm,i video recrded my last 4 or 5 builds i might be able to upload the vids to you tube for you.

and olskool guy has some really great knowlege as well.
i like alot of his ideas.

This case has built in fans...what do you guys think about it.
Hey Charlie, I'll PM you now and thanks!
