Also, many coolers come with a small tube of paste or with paste pre-applied. Check the product information before you run out and buy some (though you'll need to re-apply at sometime, I guarantee it, so buying some now might save you frustration during the build if you smudge what it comes with).
Just get whatever has good reviews within your budget. Arctic Silver is one of the well-known ones, but performance between entry and high-end is within a few degrees of each other.
300 watt single-GPUs. I'm okay with it if performance justifies it though. Still waiting for info on Polaris though so I can see if I should get a freesync monitor.
Corsair and EK will replace any parts their AIOs leak on within the warranty period. If you need the performance or can't fit a big tower in your case of choice, then go for it (and I think the H100i GTX just looks straight-up smexy).
22190002 points currently. It's only not folding when I'm gaming. Rig's in my signature. I actually got my GPU overclock up 20mhz yesterday after figuring out I can push it higher since f@h doesn't really use the memory. I hope you get enough data!
Edit: it might be useful for you to get the team data in addition to specific member data so you can see what we're doing as a whole.
What motherboard do you have? Some ASUS boards can fit little cards in the M.2 slot and run a cable to the SSD. Not sure if it'll fit under a card though, and you have to have bought the 2.5" version of the SSD.
I'd say just get yourself the basic Aurora package and wait for another "all ships flyable" weekend closer to the game launch to upgrade. Ship balance and flight mechanics are bound to change between now and launch, so I wouldn't go spending a bunch of money on a ship you might not like in 3 months (although you can earn everything in-game too, so I guess it's all a moot point with enough patience).
