Was starting to wonder if Id ever get to build my 5th build. K5 will be my 5th full build, I built my first system "a rebuild"  back when I first started with eVGA, Ive been through alot since then, like most of us in real life. With Kirk back, Ill be doing a custom case, Ill be building into my desk. And a new top for the desk.
Specs, Heavy on the ISH...
i9-9900K &  Z390 eVGA or  Z390 AsRock Mobo
Mushkin Enhanced Redline 32GB (link) $329 atm_10-5-18
Intel 660 M2 SSD 512GB_Linux, 1TB Windows(link) $190 atm_10-5-18
Seasonic PRIME Ultra 750W Gold (link) $130
EK-D5 Vario Motor (link) for a D5 X-Res CSQ $80
EK-Velocity - Copper CPU block (link) $80
EK-CryoFuel Navy Blue Premix (link)
EK-DuraClear 9,5/15,9mm (link)
EK-ACF Fitting 10/16mm - Black (link) 
Alphacool Monsta 280mm radiator (link) $120
 
 
Y-adapter for the drain (link) and (link) ?
 
EDIT:

 
 
 New desk corner will get upgraded later. Was also gifted an EK-D5 x-res.

 
Nice project ahead of you.

Wait... Kirk from lazerwerx is back?

Looks like it's going to be a nice build!

Cool stuff, I'm still around.

I like the project name. :)  Can you fit a thicker rad in there? I really like XSPC rads, but I prefer the RX series. It offers a thicker rad with less fins per inch, so you can run lower speed fans. The one you listed is a nice rad, I just try to use the thickest one if possible. It's great to see Gone Cruising back in the game.  Are you going to use soft tube or hard line this round?

Smart choice to have both 120 & 140 fan use. That will give you lots of options. I have no doubt you love the case, he don't play around.

Ideas for the loop, Loop part 5, using a T-fitting to the drain the hose to outside the case?

Nice project... T-Spliter or X-Spliter as in my case are best for Drain Valve.
This is how I plan to use... Male to Male Rottary will go to pump...
 

 
Only one guy ask me to sell him fittings and I think I will use these...
 
I didn't saw they have new changed models and I would order them earlier... 
 

 
You ask for radiator... Only this... Nemesis GTR/GTS depend of size.
If you can afford and if there is near you. In Europe they are big problem but if I need them I got 30% discount in store in Poland.

EKWB GPU Blocks/ CPU Blocks, Monoblocks/ Pump/Res Combo, XTops, but radiator Hardwarelabs.
And it's logic, they only make radiators. 
 
You can use top inlet on your scheme and than you will get rid of huge peace of tube under number 4 (from radiator to pump).
Because of that more top ports are welcomed, you don't need to use them, but they are there if you need them.
 
 

If you think about 360mm vs 420mm you should first to estimate and fan options and thickness of radiator.
420mm is better, even best new radiator fan Noctua NF-A12x25 PWM have adapters to work on 140mm radiator.
And all holes are closed ideal for perfect pressure through radiator.

Just go for it and choose 420mm.

2nd vote for the 420mm

Update:

Ill clean up post one in a few.

I am looking forward to this build with you! I'll start playing around with your design and see what I can come up with!

I did forget to add 2.5 SSD's screw holes on the inside side panels?
