For a cpu cooler, I suggest an air cooler. Air cools about as well in a decent case, costs less, is quieter, and more reliable.
I hear too many tales of woe when a liquid cooler leaks.
I might suggest Noctua, NH-D14 or even U14S.
Any case with at least 2 120mm intake fans will do the job. Looks count, pick one that appeals to YOU. I like simple cases like the Antec 300-two. Lian li makes top quality cases like the LIAN LI PC-7B plus II . A front intake washable filter is a plus to me.
A GTX680 needs about a 600w psu. Even a GTX780 or titan could use a 600w psu. If you really want to plan for sli, you need 200w more.
Whatever you do, buy only a top quality psu like Seasonic.
Here is my canned rant against sli:
-----------------------------Start of rant----------------------------------------------------
Dual graphics cards vs. a good single card.
a) How good do you really need to be?
A single GTX650/ti or 7770 can give you good performance at 1920 x 1200 in most games.
A single GTX660 or 7850 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single gtx690 is about as good as it gets.
Only if you are looking at triple monitor gaming, then sli/cf will be needed.
Even that is now changing with triple monitor support on top end cards.
b) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.
Your psu costs are less.
A GTX660 needs a 430w psu, even a GTX680 only needs a 600w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.
Even the strongest GTX690 only needs 620w.
Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.
c) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
The benefit of higher benchmark fps can be offset, particularly with lower tier cards.

d) dual card support is dependent on the driver. Not all games can benefit from dual cards.
e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
The Maxwell and amd 8000 series are due next year.

On the ssd, I might avoid the vertex. It has a bad track record:

A top brand like Samsung or intel should cost no more.
