Please HELP with an AWESOME Build!

Alright, here we go. Posted a couple builds before, and wanted to see what improvements I could make on this one based on price to value ratios. And I would prefer liquid cooling for the CPU, and maybe even for the GPU. I don't know if you can get those. Anyways, here it is:

Intel Core i7 4770K "Haswell" CPU
Intel 520 Series 240GB SSD
ASUS Sabertooth Z87 motherboard
Corsair 800D case
EVGA GeForce GTX 780 4GB GDDR5
WD Green 3TB hard drive
Kingston HyperX Beast 16GB 2133 mhz memory
Antec HCP-850 Platinum 850W power supply modular
Hydro Series™ H100i Extreme Performance CPU Cooler
A50 ASTRO EDITION headphones
Razer ouroboros mouse
Mad Catz® S.T.R.I.K.E. 5 Gaming Keyboard for PC
ASUS VG Series VG278H Black 27"
RAZER Goliathus Fragged Gaming Mouse Mat
Asus Black SATA Internal Blu-Ray Drive

800D is a big space to fill. Without a proper loop in there the case will dwarf the rest of your parts. 650D, Shinobi XL, 540D, Switch 810/820/630 would be worth a look..... my 2c anyway.

If you are after a AIO cooler for gpu's then maybe something like this is worth a look.

If this was me i'd go for the H220 over a h100i I am speaking from experience here, but as you want a water cooled GPU you could buy a titan block and link it to a h220 but I would rather make a LQ system from scratch.

If you want my reccomended Custom LQ list repost

So, so, so, so many things I would change. Budget?

rather this please
