My D5 pump died due to what turns out was particles from the rads that I never flushed when I built the system originally. So I decided to get a new case, pump, and a few fans and flush and clean the system before rebuilding. 
I wish I could have built a new system,but with the pandemic situation around here I've lost my job and am working part time to pay the bills...but that's all it covers while I keep looking for FT work. 
Anyway, it's pretty simple but I think it's the cleanest rigid tubing build I've done yet and I like it a lot :) 
You can see the details, if you're interested, in my ModsRigs link.
So...on to the pics.
 
 
 

 
 
 
I wish that were so; but while this case offers a lot, it favors thinner radiators. The bottom one can only be 120mm wide, which rules out most normal and thicker rads and you can see the one up front at 133mm wide is overlapping where fans or another radiator could go. Ideally the front one would be narrower but not much thicker because it would not have room in front with the bottom rad. Up top, there's ony 55mm of usable spaced before you're covering up the vrms. I initially tried a full size on there but with fans, it came down over the the memory as well. 
 
All that said, the cooling is actually better with this case and thin rads than the thicker ones I had in my Corsair 900D. Not by much, but at idle and gaming this rig is 2C cooler. 
 Edit: it idles at 31C in my office that averages 25.5C and gaming it averages 41C.  
 
 

Nice Rig
 
Interesting drain installation
 
+1 given in your Mod Rigs

 
Thanks for the +1!
 

 
 

I have the same case and I replaced my 3 EKWB radiators with Alphacool cross-flow variants. I used the ST30 (240, 360 & 420mm x 30mm each) radiators and agree with the sentiment of wider rad support in this case is a challenge. A PE 240 in the bottom is too wide but a SE will fit (I use the hard disk cages so I was limited to 240mm). Even a EKWB PE 240mm rad mounted up top interferes with locating pins in the top panel on the T/G side (had to Dremmel a couple of them off to make it work). I know there haven't been that many reviews for this case but I think Phanteks should note the maximum width for the top and bottom radiators on their website.
 
Coincidently, I'm also changing my EKWB res/pump over soon as Singularity Computers to sends out my new Proton unit that was ordered a month ago and only just came back into stock. My old pump/res will be moving over to my test bench.
 
+1'ed your Mods Rig.




Thanks for the +1, I returned the favor  
And yeah, that was one thing I had never thought about before getting the case was the width restrictions on the rads. I had read about the bottom rad restrictions from a review, but I had not thought the same applied to the whole case. 
 
I am amazed at all the rads you got stuffed into your case, and love the distribution plate-that must give a lot of routing options. 
I would love to change out the current rad to newer ones like this Bitspower one.
