Case Dilemma: 900D or 750D for WC Build

penance
Go to solution Solved by airdeano,

 

Ended up pulling the trigger on the 750D. I have the parts listed below for my WC setup, went with 7/16 tubing and 1/2 barbs I have read you can do this and not have to use anything to hold the tubbing down. Thoughts?

 

Alphacool NexXxoS UT60 Full Copper 240mm

Alphacool NexXxoS UT60 Full Copper 360mm

EK-Supremacy Clean CSQ - Nickel + Plexi

I believe I will have to use some sort of SLI fitting as well, still looking at those.

 

 

looks good, fans?

 

only issue i can bring up would be the stubby fittings might be too short in this

idea of having a tight radius will not have a good enough support to hold a seal.

i'd toggle the idea with the standard barbs with some grab, because of not using

clamps. i love the 7/16" on 1/2" barb, but in a tight radius loop you might need

length on that fitting. just a thought. got the order put in yet?

So I have hit a dilemma on case choices for my next build which will be my first foray into full blow water cooling. I have been torn between the 900D and the 750D and just can't pick. I like the looks of both but am concerned on the 750D if it will provide adequate cooling options. I have read with the 750D you are looking  mainly at a top mounted 360 Rad and a bottom or front mounted 240. I am looking to cool my 4770k and 2 GTX 780's and curious if that would be enough cooling or should I step up to the 900D and look at a 480 and 360. Thanks for any help!

i think the 750d will do fine because a 360 and 240 rad should be enough to cool your components properly.

750D is basically what the 800D should have been with a 360mm rad mounting at the top, 240's at the bottom and front also. I personally would get the 750D as it will be enough to cool your stuff adequately with the proper fans

750D most definitely, the 900D is almost absurd in size however the more space you'll have it'll be good to run a light server on it or maybe a fully water-cooling built however its too boring and looks awfully tacky.

As long as the radiators you're using are about 30mm or more in depth they'll be enough cooling surface area on a 360mm radiator and a thick say 80mm  240mm radiator

for a CPU/2xGPU build all you really need is 360x 60 and 240x 60 and 5 quiet high

static fans. to shovel this into a 750D will take some handy work as the roof 360x 60

will be a big concern. the motherboard 8-pin interferes with the rad/fan and gives you

two options: 1. accept it, 2. change to a 45mm roof radiator and possibly accept that

warmer temperatures or louder fan noise might be inevitable. i've fitted a Hero, MPower,

RIVE, Z87Pro, Z87-UD4H and all had 8-pin issues with the rad/fan. all accept the RIVE

could be deal breakers as the 8-pin is slotted far left and is dead squeezed mashing on

the motherboard (with some good pressure). the 240 on the front intake is a sore thumb

as the front panel/filter really cuts air flow down to a concerning level. so most go for the

floor, plus makes tube routing a lil easier. how ballsy your mod skills are and none of it

is a concern.

i haven't had one yet, but for no worries other than how to tube the case without a

spaghetti look is usually the biggest concern on the 900D, oh and how to pay for it and it

is SOO OOOGGE!

Airdeano I saw your post previously on the 750d which had really pushed me to looking at the 900d. I may be able to live with the 8 pin issue as I am currently dealing with this on my H100i in the roof of my R4, however not sure if this is as tight as what you are referring to.

to bolt up the roof rad, you'll be off .250" so you'll have the pressure of the radiator

pushing in on the 8-pin, forcing pressure to the motherboard. the RIVE had less but

not by much less. it'll be a more pressure than your experiencing on the R4. the R4

at least had some mod room for a work around, here you have minimal at best.

@d33g33 offset his radiator and drilled new ventilation in the roof and now has more

choices of radiators.

if you have the cash, have the space and aren't moving your PC around, go 900D. but I like bigger cases simply cause I have trouble getting my hands into the small ones.

I really like the 750d and I'm starting to lean that way. Now just need to start planning out the parts and hoping my AX760 is going to be enough to power everything.

I just watercooled a 3930k and 2 780 TIs in a 750D with 1 360 rad and 1 280 rad

You can have 360 + 2x240 in 750D so it should be fine for almost any kind of system

Well,

 

like I use to say always a matter of personal choice and money for the 900d isn´t that cheap, but then again it is made for enthusiasts and a real enthusiast never whines about the price ;). I´ve got the Corsair 900d and I´m running 2 watercooled custom loops in it. I couldn´t be happier. The case is enormous yes, but it gives you boat load of options. And if you want to work on the components you´ll never run out of space.

 

I.E. I´ve got dual lighting in it with 4 12" cold cathode lights and it would be easy to fit more of the into the case and hiding them just like the others and just to get a neat look.

 

But IMHO without WC the Obsidian 900d is a bit too much of a case, unless you are going for a case mod with a lot of visible stuff inside beside the hardware.

a 900D is cheap compared to a top of the line large caselabs case.

 

Yes that´s true the caselabs are the rolls royce of computer cases. But before I´d buy on of these I´d need to see a real necessity for my hardware.

 

But for a lot of people out there the price tag of the 900d is a bit of a shock.

The price is not really the issue for me on the 900D its that the thing is so dang big. I do love the options you get with the 900D but I like size of the 750D.

an option would be the CaseLabs SM8 22.44"H x 11.18"W x 22.38"D 

is pretty close compared to the Corsair 750D 22.00"H x 9.25"W x 21.50"D

 

 

480/360x 60 in the roof and 360/240x 80 in the front intake or floor

easily handles the CPU/2xGPU radiator support. makes a RIVE look like a mATX when installed.

Hi, I thought I'd share the watercooling build I just did over the weekend. It addresses the issue of the 8pin CPU header.

I used a Black Ice GTX lite 360 up top and a Black Ice GTX 280 in the front. To make room for the 8pin header I had to remove the decorative red ring off the corsair sp120.

Not yet, I did not even realize i got the shorter barbs, nice catch. I have the fans, 8 Corsair SP120's the quite edition ones. I plan on Push on the top 360, then push pull on the front 240. I'm going to try and cut some screws to make the front mount option work. I may end up going with a 45mm top mount Rad. I will not order the WC components until I get my case in and can do some measuring.

you might rethink the front intake radiator placement. that intake filter and front

plate really starves the air-flow and those quiets are not going to be doing a

good job of pulling the air though. either up the fronts to PE/PE PWM or move

the radiator to the floor. Jamaican Reaper on OCN has howled about this point

on many occasions as i have too. it is a weak link of the case (better than the 800D)

for air-flow. try it and draw your own conclusion.

Man I hate that too, i just like the look of the front mount better. Gonna have to think on that one. I was hoping the push/pull would assist some with the front mount but it may make little difference. Now off to read his thread on OCN. Thanks for all the help!
