Perfect things don't exist but definitely CORSAIR have best designers and when you look close their hardware that look more expensive and better than competition. Probably invest more in research and testing before launch something. Almost every products is awarded with many awards and first or in first three. And It's not only best designers, they think on modern way.
You will see Obsidian 900D and whole this thing with CORSAIR Link and monitoring and everything is one step above every other manufacturer. I mean if you use and spend money and make whole PC CORSAIR, whole PC CM, whole PC I don't know other brands(not whole 70% because they don't make everything) you will see how that is above competition and how price is similar or only little over something is cheaper. Some people call overhyped... hype and I don't know... But look close... I don't know H100 cooler, look mechanism for holding pump, look memory heatsink, PSU units, box, package, when you pay that you know that worth exactly that price...you have not feeling Ohhh this look so cheap when hold in hand...
I remember exactly, like I saw yesterday when I decide CORSAIR 60-70% of my PC. That was one black 600T with 2xHD5870 or HD5970 and H70 Cooler and Dominator RAM... I liked their RAM and PSU years before that but at that moment I figure out that is my style and how I look on PC.
Now my PC 60-70% is CORSAIR.
Yes Dominator is expensive little but that is flagship, if you imagine PC Memory you see Dominator in front of eyes.
