Custom Build in a Phanteks NV7, matching blocks and fittings help

[Vyoman]

MSI MPG B850 Edge TI WiFI -> Alphacool Core 1 Aurora White
Zotac 5070 ti (ZT-B50710B-10P) -> Alphacool Core Geforce RTX 5080 + AMP with backplate
Could i paint the backplate white, if yes how could i do it for effective cooling.
XSPC QX5 Photon 170 Pump-Reservoir Combination D5 Pump - white (couldn't find anything else in white)
I have 2x 360x60 rads from another build(going to paint them white).
Fans will be 28mm thickness.
1 rad on top -> exhaust, 1 rad on bottom -> (exhaust?) , 4 fans at the side -> intake and 2 at the back -> exhaust
The main issue is what fittings, 90°, 45° i will need and what route to take after the pump and an empty port most likely at the bottom rad from the back side, since the case has an opening.
Going clear acrylic so it will be nice if you could help me. Or maybe i should put the system together (when hardware arrives) and then take a picture and post it, that might be more helpful?

You can paint the backplate however you like. It actually doesn’t contribute to cooling at all — it only serves as protection for the PCB. The thermal pads on the backplate side are simply there to provide counterpressure for the cooler, preventing the PCB from bending too much. They don’t help with cooling.

As for how many fittings you’ll need, I can’t tell you that exactly. Especially with hard tubes, I can assure you that you’ll end up placing a second order because something won’t fit or something will have been overlooked.
The first step should be to make a rough sketch of your layout and draw lines showing how you want to connect everything. That will help you determine the minimum number of fittings you’ll need.

Once all components are installed — radiators, reservoir, and coolers — you’ll quickly see that you’ll need more adapters: extensions, angled fittings, offset pieces, and similar parts to achieve perfectly straight runs. You’ll only really see that once the hardware is in place.

Just as a note: the really good modders who build beautiful and well-planned systems often spend weeks putting them together. You’ll need a lot of patience if you’re going to work with hard tubes.
