Corsair H100i liquid cooler on GTX770?

I recently was looking into switching to a water cooling to cool my system.  The issue is the whole system could get costly so i was considering water-cooling either the GTX770 video card or the CPU.  I already currently have an H100i liquid cooler installed on my CPU.

So i guess my real question is:

Do I build the water cooling system for my graphics card with intent to expand to my CPU eventually and keep the H100i on my CPU for now?

OR

Do I try to move the H100i to my GPU on my GTX770 (if possible I know NZXT G10 bracket doesn't work) and water cool the CPU?

Both options would not require moving the H100i radiator in the case, but i would have to add a 200mm Antec radiator made for my case. it mounts under my 200mm top exhaust fan

Finally is that 200mm radiator going to be capable of cooling both my CPU and my GTX770 (with room to upgrade to a full water cooled card GTX 780, GTX 780ti etc). My end goal is to have worked up to a full water cooled efficient rig that has plenty of room to upgrade graphics cards. I wasn't really planning on SLI at this point because I am currently running a Raid 5 with 4 3TB drives and if I expand to 8 drives like I want to I will need a raid card which looks like it  will give me SLI space issues on my Mobo, but that is at least a couple years off yet.

Since this is my first water cooled build I would like to here any ideas or parts suggestions you guys have!

 Here is a couple pic of the inside, you can see at the very top the 200mm fan that the 200mm radiator mounts under.

Custom loop & a new case (your's isnt suitable at all suitable without heavy modding). A single 200 wont handle a cpu & gpu as even a thick 120.2 (240) will struggle. The quality of 200mm rads (fin density etc) isnt up to the levels of that of the more widely sold 120 and 140 variants.

Grab a case that is suited to watercooling so you wont have to do things twice and end up have a ghetto looking build. Something with at a bare minimum the capacity of having 2x 120.2 rads + fans. If always followed a rule of thumb 240 for cpu + 120 for each gpu.

For a first wc build Id grab: (parts here in oz so you'd have to source for your specific region)

  • NZXT 440 case - a watercoolers dream mid tower case. Big rads front and roof. Or there is the new 450D which is also pretty good.
  • Loop starting kit from XSPC + a few extra fittings (45's, 90's etc)
  • Find a waterblock that will fit your exact cards PCB, can check here for EK blocks. If there are no blocks availble, either sell on the card or settle with universal gpu blocks + maybe an addition of a modded g10 kracken vrm cooler.

A lot of this may seem expensive, and yes it certainly is. The thing with proper watercooling is if you go cheap and nasty you end up with a real ugly build, add to that if there isnt enough radiators you'll have to have fans @12v & loud to keep thing cool. So planning is crucial and be prepared to spend some cash. The best thing about a proper loop is silence. All you should hear is the slight whir of the pump.

Hope this rambling has made some sense. All the best with it.
