hi smicha,
I am shocked with this beast..
if it isn't a tricky question, how much cost about all components?
let me dream...
best regards

Actually it is a relatively a bargain compared to 6x TITANs on air and almost same performance.
I'll post a list with prices on the first post soon.
Rough estimation - titan 1k$ (a year ago, no 780s 6gb at that time), 3x780 1.3k$ all, watercooling parts 1-1.5k$, fittings from China for 3-4$ per unit, case 500$, asus ws 60$ at auction, cpu 250$ (3 years ago), PSU 250$ (3 years ago), hdd, ssd, ram... - lots of these parts I leased for 3 years paying about 100$ net monthly.

impressive relationship between price & performance,
congratulations

Keep this coming, Smicha =) probably this thread will be the best case study here =)
for those who seek value & not just to make bling post about "hey, look at my new pc"

hehe, reflection of Your Nicon was a nice touch =) I was thinking at first "why does he put this off focused shot here =p",
but then..It came clear i nervation with older post from other user =)..

looking for piping =) & from few fittings already installed it seems Your took a nice route! =)
& hop seen those numbers on Bech thread - respectable performance!

Great build and nice chose of STRIXes. Asus did great job on those 780 OC 6GB cards even on air cooling mine don't go over 79C and they are very very fast in Octane.

I used what I had (need to order some more of Barrow fittings - excellent quality)

EK-FC Terminal TRIPLE Parallel



EK-Multioption RES X2 250 - I gave up X3 res. mounted to the dual pump top - the dual top tits perfectly in dual 5.25 bay.



All with EK-D5 Dual TOP G1/4 CSQ - Acetal

Lewis,

Temps around 70-80 are only for 1 or 2 asus strix mounted - if there is more than one slot space between they have enough air to breath and they don't get heat from each other. I tested two of them on air with no space between them (same as for 4xGPUs spacing) and the upper one got hot so quickly to 80C, fan was set to 100%, and core clocks started to go lower and lower to about 800mhz. So yes - if you have one or two of them with space between them they are fine. But there is no way to get them cool for 4xGPU config. But on water they are showing their full power - 1250mhz on core and and 7000mhz easily, at 40C.

What is curious - MSI afterburner says - 70 % power usage at full load while rendering in Octane - anyone can tell me why?
