For less than this price CyberpowerPC will build you a vastly superior computer.
- 1.2TB Intel 750 series PCI-e SSD
- 3x4TB hard drives which you could set in RAID 5 for 8TB redundant Storage
- Top of the line ASROCK motherboard because you are wasting money so why not
- 64GB DDR4 2800mhz RAM (with room for another 64GB)
- Intel i7 5930K
- Phantek Enthoo Pro Case
- 1,500W 80 plus Titanium fully modular PSU
I think you will find that w/o the custom water loop, Xotic PC is not that far out of line as compared to Cyberpower or anyone else where air / CLC / hybrid type cooling is involved.

You can do your builds here w/ the same results as in your builds but like many sites, you will likely find Asus, Gigabyte and MSI high end boards, Asrock options are more typically associated with more budget oriented builds, tho that mindset is much less deserved of late than it has been in previous generations.

Even going further foe more premium components than those 4 builds with Twin KINGPIN Ti's and 2 TB SSD, the cost is just $4750 .... it's adding the custom water cooling that adds the big premium .... $1,015.00, using acrylic tubing adds another $400. There's the $1500 cost premium...adding premium TIM adds $130 or so and braided cables adds $100. This all goes away with a cheap CLC / hybrid solutions which provides no performance advantage over well designed and much cheaper air cooling solutions.
The reason this unit costs what it does is because any custom shop or self builder will need to spend in excess of 100 hours to do the custom cooling loop with rigid tubing as a "one of". Yes, you can buy similar or better component builds for much cheaper but they will not include custom fabricated rigid tubing.
I can't see paying Cyberpower or Xotic to build any of your 4 or my $4500 build on Xotic site as any average Joe could do it and save considerably w/o investing an inordinate amount of time. Let's say, they are making $800 on the build and saving me 3 hours of my time.... I'll invest my time for $300 an hour. But doing a rigid acrylic loop requires hundred of dollars in tools, and unless you follow someone else's build who has already prototyped all the components and insured fit for all of them, you are going to spend 100+ hours doing rigid acrylic. Those with adequate disposable income will be less likely to invest there limited free time when all they are saving is $30 per hour.
Other considerations:
1. I wouldn't recommend 4 TB drives have a very high failure rate, whereas the same model 2TB units do just fine.
http://www.hardware.fr/articles/927-6/disques-durs.html
- 4,76% WD Black WD4001FAEX
- 4,24% WD Black WD3001FAEX
- 0,70% WD Black WD2003FZEX
- 0,56% WD Black WD2002FAEX
If you want better performing Hard Drives, I'd recommend SSHDs which are 50% faster in gaming than the WD Black and have failure rates about 1/4th of the 4 TB units
2. Based upon comparison testing by Anandtech, Skylake, Devil's Canyon and even Haswell are, more often than not depending on the game, faster than X99 / 5930kin gaming with 1 or 2 GFX cards, X99 only surges ahead after adding the 3rd 9and 4th) cards. If used for both Gaming and Video editing / encoding, then I think X99 / RAID 0 merits consideration.
3. The system even water cooled and heavily overclocked has no need for anything more than 1050 watts. The 980 Ti in SLI, overclocked draws the less power than my SLI build (16 fans, 2 water pumps and 5 x 140mm of rad) and I'm seeing 745 watts peak under Furmark at the wall. At 90% efficiency, that's about 708 watts of PSU output.... sizing for 50% of max load, would be 1062 watts.
4. Titans are slower than 980 Tis when both are overclocked.
5. The Hybrid cooling lowers the GPU temp but not the VRM and it's the VRM if anything that will usually limit 9xx series overclocking.
6. 240mm Corsair Series CLC's are 12 times louder and do not cool as well as less expensive air coolers like the R1 (3C advantage) and D15 (2C advantage).
7. Again, RAID 0 offers 0 benefit in Gaming
8. If one is picking the best GFX cards, the ones on top of the list would normally be the Classified and Lightning. EK declined this round to make a block for the Lightning. OTOH, the value of those two cards has diminished in recent generations as they barely have a return on investment outside of LN2 and DICE configurations. Out of the more commonly purchased "gaming" models, tested overclock results are as follows:
Model / test fps / % over stock settings
Gigabyte G1 134.8 131.4%
Palit Jetstream 133.1 129.7%
Asus Strix 131.7 128.4%
MSI Gaming 130.5 127.2%
Zotac Amp 130.4 127.1%
EVGA SC 126.8 123.6%
One could always self build or have someone custom build a box that's better. ONLY thing that is attractive here is that someone else bought all the tools, did all the measuring up, test fit the various components and then did the final install.
