Best Case choice for water cooling build.

Corsair 750D

I second that. +1 SR-71

Watch the review by extremerigs on youtube....the Hydrocopper (aka EVGA / Swiftech) did extremely poorly. Ridiculously priced and the worse performing block they tested, especially with regard to VRM and VRAM temps.....the Titan, 780 and 780 Ti all use same Waterblocks so the review is applicable to all these cards

EVGA Hydrocopper 11C hotter on VRAM than the EK Block ..... the Hydrocopper is 29C hotter than the EK Block.....33C versus 62C !!!!

Ya lost me on the sexy thing .... I find the 900D sooo mundane and plain. Case labs makes great cases but again, rather mundane..... the Primo on the other hand appears, to me anyway, stylish, has nice accents. lighting and excellent brushed aluminum finishes. Best case I have ever used for hiding cables (no effort required actually ... res bracket hides most everything) ..... one of the few cases I have used that even hides the PSU entirely. But yes, I have to say I think white makes both cases look better. Newegg had it there last Sunday advertised for sale as of the 10th but pulled it. Word is Phanteks needs time to fill it's pre-orders before it goes on sale at newegg

But case aesthetics is a very personal thing so there is no right / wrong answer for everybody ... to each his own kinda thing. But I will say.... looks in newegg pics and looks on ya desk are two very different things..... the look and feel of brushed aluminum for example won't come across in a pic.

The 440 is sharp looking in a clean way and I recommend it often for air cooling..... or AIOs if ya into that kinda thing .... but to my eyes it just appears too small for water cooling twin GFX cards. The 750D is very tight but doable.... but the 440 is considerably smaller (only 75% of the volume of the 750D) With 8.67" x 20.08" x 18.71" where do ya fit everything ? I don't see much space for a cylindrical res in there; my guess is ya will be relegated to pump / bay res combo which hands ya both noise, and vibration issues not to mention potential seam leakage. My other concern is ruggedability....the H440 (21 lbs) is half the weight of the Primo 9.84" x 25.59" x 23.62" (40 lbs).

Not sure where ya coming from on the noise issue....what kinda fans you thinking of ? I have the case sides off with the machine sitting 2 feet from my head, it's dead silent. Using 1200 rpm fans controlled to operate between 325 and 850 rpm..... Cases don't make noise, fans do. If you are gonna stuff 1800 rpm fans in there, there's no way around it, it will be noisy. Fan noise *can* be a larger concern in highly overclocked water cooled rigs that are short on rad space as the fans blow air thru a radiator .... the static pressure and "wind" going thru the rads when at rpms > 900 creates noise. As with air cooled rigs, better to have lotta fans going slow than less fans blowing fast.

As a minimum, for 2 GFX cards, you'll want at least a 280 + 420 rad in push pull or a 480 + 360 if ya go with 120s ...... using the 440 I just don't see it all fitting with a 60mm diameter res, at least not with 11+" GFX cards.

Take a look at the Owners Club builds and see what peeps have done with them

I read the last 10 pages or so on the 440 thread and saw frequent complaints about air flow.

As for alternates.... if ya thinking 440 / 750D, the Luxe is equivalent but again, doable but kinda tight for water cooling two cards. Other than that I haven't really found anything that tickled my fancy.

Wanted a really good water cooled case?

The king of cases

I have one of the older x-ufo cases and love it more room then I will ever need

I'd guess his system's been up and running for about 6 months by now but I remember that case fondly. That case was one of those that really got the ball rolling for water cooling .... today it's a bit outdated (no 140mm rad support for example), a bit tough to fit on ya desk and no specific WC features other than "lotta space" (i.e. built in reservoir mounts, pump mounts, fan controllers) but many of today's case features I think wouldn't be here if not for designs like those back in the day.
