Custom loop is for fun, I might be able to quote one later.
If you don't want a custom loop, grab the EKWB 360mm kit. Except buy Phobya tubing.
For video capture, go software based. Buy Camtasia. Best you can get. If the editing capabilities aren't enough, you can always pick up APP.
Tower, I'd go for the Phanteks Enthoo Primo if you don't want a custom loop, if you do want a custom loop grab a Caselabs.
Definetly not enough videocard power. Go for two or three of those, or if you want to save a few dollars and still get rip-roaring performance, pick up 3 R9 290xs.
Toshiba is just gross. They're a sleazy, horrible company with a bad rep for terrible QC. Seagate all the way.
For a system like this, you'll want a Seasonic platinum PSU.
Don't get the 5960x, 5820k will be more than enough.
Thrusmaster Warthog for HOTAS.
Not enough time to find a good 4k gaming panel, maybe later. The new ASUS one is supposed to have a 1ms response time.
That is a future goal, but for now I plan to game and record in 4k on a single monitor, or triple monitors at a calm 1920 x 1080 on each.
