I have had very good luck with the H series AIO I would say the H110 if you can fit a 140 x 280 Rad. in the case.

I have the H90 and it works perfect for my needs. I've had the H110i GT and the H105. The H110i GT was actually not as good as the H105 for me... and corsairs software that works with their i series AIO's is an absolute nightmare, but that was 2 years ago... Hopefully it's been refined, but the experience I had made me never want to use their software again. The H105 didn't work out for me because the pump started to fail after just 2 weeks of use, but man... those temps were awesome when it was working, I couldn't do anything to get my i7 4790K to break 30C.
 
I would actually recommend checking out the NZXT Kraken series, those tend to have a little better performance than the Corsair units.
 
Here is a review i'd check out.

My personal recommendation is the H90 or the Kraken X61.

I didn't realize NZXT just came out with a new X62 and X52 back in November. This is a pretty decent article:

I just got the corsair h100i v2 and seems to work quite well so the h110 would probably be a decent fit if your trying to go for the bigger rad. Corsair link doesnt seem to use to many resources. I had a difference in individual cores by 10 degrees but i think it just had to work itself out. 

They are all the same (except EKWB). Asetek holds the patent to all in one pump/coldplate coolers (notice EKWB has pump in radiator). Besides lights, software, and fans, they are all nearly identical from whatever manufacturer.

I have and have used both the Corsair H80 and the H100i and have had good luck and performance with both.
 
The only thing I would do differently is skip all the fluff and pointless (for me) connections of anything i series from Corsair.

If i go with Corsair Hydro H115i, i probably won't bother using the LINK software.

I see a lot of people complaining about NZXT Kraken CAM software being unstable and using high resources. Without the CAM software it will only run in silent mode. 
 

Sounds exactly like the LINK software from Corsair. I wouldn't put any stock into the software. The best AIO's right now are the ones with the 280mm radiators... I suggest purchasing better fans though... The fans that come with all of the corsair i series units are extremely loud and they become a distraction when they ramp up to 2800+ RPM's. The fan that came with the H90 was not too bad, but the ones with the corsair LINK software are high RPM fans with sleeve bearings, so they get really loud.

A great point RainStryke! That's exactly what I was thinking regardless of what brand you choose. Most use a cheaper fan. 
 

Corsair 280.  Change fans to some of Corsairs high SP mag lev fans.
 
Get some good tim, like grizzly or something similar.

Loyal corsair H110

What about and EK Predator?  

Or are we looking to keep the price around the 75-125.00 mark?

EK Predator has been discontinued.  New version will be out in March.  Just hit the news a few days ago.

Around $125 mark, i don't plan on pushing i7-7700k to it's limit. 
 
 

I'll reaffirm the Corsair thing again.  H115i or H110.  That way you get a 280mm radiator.

Best is EKWB Predator, than CORSAIR H115i.
EVGA prepare soon some nice AIO system, performance are probably similar to NZXT Kraken if same manufacturer produce them.
But pump look nicer than any other model and some cool fans.
 

 
Probably look excellent installed on CPU and Hybrid GPU with some LED strips in case.

I have CORSAIR H100 5 years.
I would like to have custom loop but probably I would never build that.
If CORSAIR H115i is same as EKWB Predator than better H115i.
But EKWB Predator is good because he could keep and graphic card on low temperature for gaming, without noise.
 
I would build EKWB X-RES D5 100 PWM, 280mm or 360mm Coolstream radiator, Supremacy EVO and Waterblock at least Thermosphere for EVGA Founders Edition. That would be my perfect cooling configuration. That's around 350 together with fittings. Same as Samsung M.2.

For the sake of it, lets say EKWB Predator 280mm beats Corsair H115i by 1-5ºC, is that really worth over double the price tag and shorter warranty length. At damn near $300 price tag, you start to get into basic CPU custom loop territory.
 
It would be nice to build a custom loop but i don't want to spend that kind of money.

I would just stick with the corsair. It isn't worth the extra $$$ to me and Corsair is tried and proven in the AIO department. The last one I owned went strong for 3 years and is currently still running in my buddies setup over a year after that.

Think i'm going to go with Corsair Hydro H100i V2 240mm.
