I wouldnt say that. You mention watercooling and another card and monitor. You dont "need" to have these. From my point of view watercooling should be to lower your temps and also lower the noise, making you have a nice OC and overvolted system reasonable quiet if done proper. First of all, your components are overkill to beginn with. If you are gaming there would be no need to even buy those from the frist beginning and if you would make a quad titan or similar system then why on earth even choose a quad core i7 4770k from the beginning and such a "questionable in-win??lmao case"?
Personly I believe you can both thave a cost effective and nice looking system and here the small details are important. Im more of a simple person, single gpu, single 120-144hz monitor, single waterloop, big case, no bling bling BS. People underestimate the weight of building the system according to the games you play and how you want to play it. Just because you can spend 4k on a rig, doesnt mean it will perform better in games or suit your "gaming needs" or that the extra 2k you spend will give any real "value" in terms of fps per dollar. My system for example is 100% built after my needs and how I want to play games, believe it or not. Thats the reason I stayed on my i5 and single gpu setup and keept my watercooling when I made some kind of upgrade to my system.
For example OP, the motherboard, memory and the PSU are severe overkill for gaming, and even if you would OC you would be extreme limited by other factors, like the h100i cooling and the lack of space in your case for mounting rads. I have a hard time understanding your mindset behind your spefific build really. What was your goal? I see no reason for people planning on building a z87/z97 system to get a high end mobo and RAM, because the OC will be 90% limited by other factors.
