Yeah true that, but the H110i is only 3 euros more over here than the H100i V2, I also would want to futureproof myself since I might be upgrading to Z270 Platform.

Credit to @Starelementpokeand @Energycore for helping out with this long-awaited refresh of the old PSU tier list by Aniallation (who previously went several months without logging in), leaving the old list in need of help. This is simply an update of the list that was flawed in creation by the PCMR subreddit and in dire need of a refresh.
 
This list is subject to change as new PSUs come out on a regular basis and standards may change or issues with units on the list may develop. A list of PSUs awaiting a tier on this list is at the bottom.

How do you even grade these things? ***
But I don't like Tier Lists!!!!111!!!!
 

From my own experience it all depends on you hardware, I tried to do It with a Pentium E5500 and a Radeon HD 6570 a few years ago, went pretty horrible with the drivers and stuff, finally gave up.
After a few years when I got my 4690K+7870 I tried again, this time everything went A LOT easier, it all depends on hardware,
right now I have Triple Boot with Linux Mint 17.2+Windows 10 Home and Hackintosh El Capitan 10.11 (too lazy to update), and everything is working like a charm!

I've modded my Corsair SPEC 01, I've taken the hard drive bay out, and the two hard drives that I have, I sticked them with velcro in the optical drive bay.
Now I think the build looks a lot better, tell me what you think. 

Sorry for crappy picture quality.

That looks good, for something like this you will probably want to purchase colored/tinted acrylic directly, for the thickness you will want to keep it pretty thin something like 1/8" would be good especially if you chamfer the edges so it matches a similar thickness to the original side panel. For mounting you have a couple of different ways to go about it either to have it bolted through with bolts/thumb screws or to make something magnetic and latch it in place. 

Thanks for the reply!
We finally resolved it,
it was a Drivers problem, we installed new drivers, apparently the drivers that we used didn't let us do multi monitors with passive DP adapters.
