Hurray for huge post.
As others have said, the 980x is a waste, unless you're doing multi-threaded encoding/rendering or Folding@home (even then.. a bit extreme of a price)
Grab a Gigabyte UD3R + Intel i7 930 - it will perform similar in games, without the huge price tag associated with it.
I don't know what RAM you're specifically looking at, but it's the wrong stuff. You want triple channel ram.. three 2 gig modules. (6 gig total)

Or the Trident series

that's the canadian site, reference the part numbers for wherever you're purchasing from.
You say "at least 850W" but probably don't realize the highest end video card with your setup is only 450W at peak. You can SLI EVGA GTX 480sc's with a 850W.. and still have all the watercooling and extreme fan setups.
Look for something semi or fully modular.. Seasonic, Silverstone, Corsair are popular - I use OCZ power supplies too.. but some don't like OCZ PSUs for some reason. XFX are good - they are basically rebranded Seasonics - whatever is in that window that's on sale.
If you're going for epeen in a PSU, the Corsair AX850 is dressed to impress. (and.. is a wicked PSU to boot)
As for video cards, I wouldn't go with the 5770 to impress.. I am an NVIDIA fan, so i'd probably go with the EVGA GTX 470 as a base.. or a 480 (sc)with your newly expanded budget. If you're an ATI fan, i'd go with an XFX 5850 or 5870. In both setups, ATI or Nvidia, i'd be getting a second down the road if you want the epeen.
As others stated, grab a 120 gig or so Sandforce based SSD - OCZ Vertex2 being the best out on the market right now. I'd grab a second 1TB sata hard drive for storage.. the Samsung F3 is the fastest, and the WD Blacks are popular.
I don't have personal experience with the Lian-Li case you talk about.. but cases are all a personal estetics thing. If you're watercooling, the CM HAF-X or ATCS840, and Corsair 800D are up there for watercooling favorites.
Watercooling loops are a whole different story for a whole different section of this site.. and I don't have the time to type all that out right now, lol.
