Rate my water loop

Just looking for feedback and suggestions as this would be my first time water cooling my PC. The case is an antec 900. If I did the front mount I'd have to cut out part of the drive bays to make it fit. If I did the rear two I would have to run slim rads and might still have to move the top one more forward to the front of the case. I plan on using a cylindrical res with a built in pump, but I'm open to suggestions, etc. Thanks in advance for any suggestions!

No matter what you decide to do neither of those setups provide the necessary air flow over the motherboards VRs around the CPU socket. You'll have to supply some additional air flow over the area, unless of course your motherboard has built in fans to get the job done, some do.

Didn't think to add a drain port, maybe a T fitting by the front rad or before the res would be good? Also as far as airflow over the motherboard you don't think that 120mm side fan blowing onto the GPU/motherbaord would be sufficient? It sits a little higher in reality than my drawing, probably a little bit above the middle of the motherboard. Motherboard doesn't have any built in fans, but the RAM I plan on buying is coming with a little RAM fan, but that probably won't be too much help on the VR/chipset. Thanks again for the suggestions, really appreciate it!

Here is the planned build, just waiting and hoping GPU prices drop and they become more available again lol.. I do plan on overclocking both CPU and GPU after I've had the build for a bit.

Intel 8700k
AMD Vega 56 or 64
Asus ROG Maximus hero
3200 ddr4 16gb
EVGA g3 850 PSU

I'd like to get into water cooling for the obvious cooling benefits but also as a hobby. It seems like a fun project to take on.
 
If you want to get into liquid cooling, start with more appropriate case.
Like i get the fun of modding cases and my first loop went into CM 690 which eventually was very heavily modified.
BUT, you have a CPU that can easily do over 150w (overclocked under load) and a GPU that can go to ~400w.
That's over 500w to deal with. And unless you are ready for the jet noise in your room, you need significantly more radiator surface.
Another problem with this config is that the exhaust rad/rads will be reusing the air from the the intake rad which makes them MUCH less efficient. like air after passing through the rad easily raises by 10C (we are talking about system under load with moderate, under 1500RPM, fan speed).
so get yourself a nice liquid cooling friendly case with decent airflow and support for at least 6x120 rad surface. optimally 8x120 or 6x140.

Yea I was worried this case wouldn't cut it. I just like the looks of it lol. Any suggestions on a water friendly case? I've seen a few, but they don't seem like they would have good airflow to the rest of the motherboard.

If you plan to do any overclocking of these watercooled components, you're likely going to want to use at least two, 240 rads. Also, your case airflow is going to suffer if you plan to mount radiators over all the fan mounts...while radiators do allow air to pass through, you're still going to want to get heat out of your case.

Thanks again for all the input. So far I like the thermallake view 31 for my future build but might watercool my current set up just to get some hands on experience with water cooling. Do you guys think if I did the top setup and added another 120mm fan to the front above the other two and did a 240mm rad top mount instead of rear mount that I'd have adequate airflow and cooling?
