Essentially laid out like this cosmetically:
 

 
360 RAD > Reservoir > Motherboard > Void Space > Reservoir > 360 RAD
                    > PSU         > Video Card
 
Looking at turning my tube reservoirs into pump combo on each side (EKWB).  The pump has to be in the front because it will back to a flat surface.

When I'm making this conversion, I get a little lost where exactly the best spots are to put the tubing.  Each side will only have an inlet/outlet for RAD and CPU/GPU respectively.  There is a total of 4 hook-in points.  Should I bundle them both up top or give them room to breathe between.  Fill in the dot kind of thoughts?  Fill and drain exist as separate locations.

I'll be repeating the method on the GPU side.  Image in my signature is dark, but my modsrig link will give a few pictures in better lighting.

Long-term vision idea here.  With the hybrid K|NGP|N I was forced to behead my water loop for the GPU while I wait on the hydro conversion to surface.
          
 
 

I have seen your mods rig. I am confident what you go with will more than likely look pretty nice. Your whole room is a dream man/people cave. 
 
Those distro-plates are really nice when you can incorporate them. Current set-up is the two reservoirs on each side isn't it? Looks like you have room for those distro's you are wanting to use. Lot's of tubing run options there. 

I would like to make 1 small suggestion if thats okay, you should look into 180 degree pcie adapters that will clean up those cables for the grphics cards I have 2 of them with my 3070 and they hide the cables very well.

Have my distribution plates and radiators in place. Waiting on the fans. Going to start on tubing too the distribution plate today.

Latest. Waiting for hydro convert kit, finish gpu tubing, finish led case border, and rad fans.

Opinions.
 
I have Purple, Green, and Clear Cryotfuel from EKWB.  What should I put in these tubes?
 

I’m dealing with kingpin issues right now. Only thing holding me up now. :-(

If you're running separate loops try purple in one, and maybe clear in the other. Kind of like intake/ exhaust. Or whatever your taste prefers. It has worked well so far. :)

Wrapped everything up.  Cussed the entire time trying to put it back on the wall.  Had to set it on PVC pipes on my desk take a breather, then hoist it the rest of the way.
 

The fans themself are nice.  I think the controllers are garbage out of the box.  They seem to be acting better after I upgraded them.  Originally I couldn't get them to sync color with my motherboard, then I couldn't get them to let me adjust the RPM.  I prefer the border effects over the lit up fans.  Decent effects if you want something unique for your fans to do.  After I got through all the pains, they have been performing well.
 
My PC doesn't like internal USB 2.0 hubs from the motherboard 2.0 internal ports.   About to split my USB 3.0 and step down one of the legs to a USB 2.0 and see if that performs any better.
