update 1/13/2018: Decided to finally let this machine live up to its name and go full custom loop water cooling and max out the capabilities of the much vaunted NZXT Manta.
Going with the EKWB DDC pump with the 250mm reservoir, dual 280mm radiators and the Gigabyte 1080 TI waterforce waterblock version.
This has been pretty much the most punishing build I have done so far for someone with my gigantic hands, the front intake radiator is EKWB's own SE 280mm radiator (I opted for standard thickness as the space allowance for the reservoir was really to the edge) which fit fine. HOWEVER, the EKWB radiator ports DO NOT fit the top radiator cutouts hence I would recommend that people just get the 240mm version, luckily I had on hand a 3rd party OEM 280mm radiator which ports fit so snugly that I had to tap it in from the side to even go in.
I could not do a direct connection across the two radiators on the right side of the case due the way how things were aligned so I had to flip it around and run it from the tail end of the case. Given that I wanted to keep my 120mm RGB fan, I had to give up on that cool Multiport top that EKWB has and go with a slimmer top cap with a fillport which luckily gave me enough space to comfortably replenish the reservoir with a 90 degree pump bottle.
I wanted the main emphasis to be the reservoir in the middle but they did not sell tubes in black for 10/12mm but I think the routing worked out okay in the end with some minor 'abit too long' here and there.
The reservoir actually hits the RAM sticks and the CPU block connectors using the default mounting hardware but if you look at the pictures of the pump mount, you will realise that I built an offset mounting plate out of ice cream sticks sprayed matte black. Yup, to lessen the stress of the weight of such a large reservoir, I used one piece of the 6cm tube bracket and slotted it with a measured and cut piece of acrylic hard tube to rest on the gpu. All it takes is imagination to solve an issue.
Please feel free to ask me about fitting issues (I've hit alot of them during this build) if you are looking to build a water loop for this beast of a case (NZXT curved glass please? yes?)
Glad to finally let this machine live up to its namesake as the Deepsea Challenger and finally breath fully in water.
update 8/6/17: got the nzxt puck online since they dont sell it where im from. couldnt get the purple one but im happy to report that the puck has no problems holding gear on the Manta's curves. pics above
Sold my old mATX GTX 970/i7 4770 system and used the money to build a new system for a new year.
Construction took a while to source between local retail and amazon with price savings being a top priority for all decisions. It didn't help that the NZXT x62 was delayed for about 3 months from where I come from.
I know that its not a fully custom water cooled setup despite the name but hey, it's something for the mark II to look forward towards.
Using bitfenix's sleeved cables and hand stitched them with multi-coloured thread.
If you do not recognise the ASUS z170i itx motherboard, I had all red accents on the board repainted into a flat black using heat resistant spray paint. I had also installed a painted copper pipe piece to hold up the graphic card at the end to straighten up the sag.
I also have led connectors coming out of the case via the bottom to link up the desk lights to take advantage of the CAM integration hence all the major lighting sources are controlled via software on the desktop.
Designed a label and logo and printed them on clear vinyl and slapped them onto the front and interior of the case as in the pictures.
All in all, including the money offset from selling the old system, spent around USD 1000.
Problems: The x62 pump header DOES NOT fit well with RAM that have heat spreaders on a itx board. The inlet and outlet joints are pushing hard against the RAM displacing them about 2-3mm to the right. Just pushing in the ram itself requires a substantial amount of force using both hands which thankfully still works so far.
x62 + 2 x NZXT Hue+ units on an itx board with only 1 x 9 pin usb header took abit of work to figure out with the splitters.
The thing weighs in the ballpark of 15kgs, even though I put everything in myself, I still wonder where the weight comes from.
Be warned, Corsair link and NZXT CAM software controllers are still super dodgy right now so it takes some wrangling to keep everything under control.
Please drop me any questions below and I'll try to answer them if I am able to. Thanks for the view.
