would like feedback on my slade build

First time DS buyer (and, returning to the PC world after languishing with a 5 year old iMac)

Saved Ticket #: https://www.digitalstorm.com/configurator.asp?id=1405836

Specifications:
Looking for general feedback on this build:
1) do any choices look severely out of whack?

2) I upgraded the power supply to 1000 W based on seeing other 2x SLI builds doing the same, and an online calculator which put me right around 750 W or so

3) Does this have sufficient cooling for modest-decent overclocking?

4) I browsed through the different mobo options, and just dont see how 1 is particularly better than another. Do the more expensive options provide anything substantive?

5) I've got a 4k monitor. Can I get full resolution performance out of it using this setup? It looks like I'll have to use the DisplayPort connection to make this happen, which it looks like all the mobo options support. Do I need to get the optional "ASUS ThunderboltEX II Adapter"? I'm not entirely clear on what this adapter does if the mobo already comes with a displayport connection

Thanks

To go with/add on to what bpratt was saying, if you plan  on OC'ing you graphics cards I wold opt for the ASUS Strix which is only $32 more.  They are easy to overclock and perform quite well.  the down side is I'm not sure how they would work with the cooling in that case since they dump the heat into the case.

As you can see in this image, the drive cages have been removed from behind the intake fan(s).  by upgrading (adding more) Corsair Air Series Airflow fans (you can get either 3x 120mm or 2x 140mm to fit as intake fans) you'll get quite a bit of positive pressure and airflow which should adequately cool your sli vid cards. 

the case is meant to be used with the top vent cover on.  it is considered a "sealed" case for acoustics.  you should be able to run the fans quite fast and still achieve good acoustics.  its predecessor, the 550D, was capable of this and similarly designed. 

i don't think there is room for push/pull fan config on the rear (exhaust) fan/rad config, due to the limited space and mobo interference.  check with DS if this is a possibility as it would be beneficial, imo.   i would skip putting fans in the top (roof) location, even though it is an option.  you would have to remove the top cover, thus voiding what this case is designed to do.  if acoustics aren't your top priority, and/or thermal performance is, i would suggest using a different case (i.e. the Velox).
