1st Build! Please help me with some advice.

you can spend way less for more performance you know

get this

-better to use the newer stuff rather than the old
-if you want your CPU to be cooled by water, get a custom raystorm kit. AIO units are cheaply made and pretty close to useless if you ask me as they dont perform better yet they cost more
-scamtooth a) heatshield does nothing and b) has same features as a much cheaper board. also note, boards will not affect your overclocking much if you arent using liquid nitrogen. the differences are minimal at best and you can spend the saved money on things that actually do something.
-faster ram does nothing
-the 760 itself cannot drive the extra vram manufacturers tack onto the pcb. its a marketing scam.
-a SSHD does not come close to a hard drive and SSD configuration. no where close
-platinum efficiency is not needed and you can spend way less for the same quality
-better case
-i personally would get a high quality IPS panel over a faster TN panel. with IPS you get much better colour accuracy and viewing angles. things generally look more movie like in quality. with your TN panel, you get more speed, but then colours are crap, viewing angles are crap, and it costs much more
-windows 7 is cheaper and better. if you want to take the trip on learning windows 8, go ahead. If i were to use windows 8, id have to use ex7forwin8 to completely disable the metro interface. the only benefit of windows 8 so far is the ability to pause file transfers, the better search function, and the slightly faster boot times that you arent going to notice much when using a SSD
-if you arent going to watch blu-rays, return the drive. optical drives are accessories that arent going to be used in this day and age

qualified lists mean nothing when the manufacturers can never possibly test every single ram kit out there.

as for your calculations, they are pretty much irrelevant. the reason for that is that the CFM ratings are never correct even for high end fans like noctuas. if you want positive pressure, all you need to do is have more fans pushing in with filters than exhaust.

speaking of fans, the stock fans on the arc midi r2 will be more than enough. loading the entire case with fans will do nothing and just increase noise. an example is that i dont bother with case fans as they do nothing for my rig even though i have a supposedly hot case. replacing them is useless as they all generally perform the same (except for noctuas). if you want lights (which are useless as you can spend that money on something else more worthy), get 2 30cm strips of bitfenix alchemy LEDs. they are bright as hell and much higher quality.
