I am posting this because i have spent more the a month going through all the possible builds and parts that would suit what i was looking for, which was a compact, air cooled (air travel) system able to coop with the latest software requirements, from gaming to video and photo editing.
I have considered various setups and i have now built the system with the following parts.:
CPU Intel Core i7-4790K 4.0GHz Quad-Core Processor
Noctua NH-D9L 46.4 CFM CPU Cooler
Motherboard MSI Z97I GAMING ACK Mini ITX LGA1150 Motherboard
Kingston HyperX Fury Black 16GB (2 x 8GB) DDR3-1866 Memory
Kingston SSDNow V+200 240GB 2.5" Solid State Drive
Samsung 850 EVO-Series 500GB 2.5" Solid State Drive $163.99 Free two-day shipping with Amazon Prime $163.99 Amazon
MSI GeForce GTX 980 Ti 6GB Video Card
Silverstone SG08B-LITE Mini ITX Desktop Case
Silverstone 600W 80+ Gold Certified Fully-Modular SFX Power Supply
Silverstone SOD02B DVD/CD Writer
Silverstone AP182 170.0 CFM 180mm Fan
Cable management was Ok. I did not opt for any 3.5 HDD so i could route part of the cable where the HDD was supposed to go. The GTX 980 TI size fits very well and leaves enough space for cable routing as well. The SFX power supply is just a blessing with flat cables.
I did go with MSI parts because i have build systems in the past and i found in MSI a good partner.
Going on noise and temperatures: With the AP182 fan i can adjust the RPM, below 1000 rpm the case is silent and, with everyday stress, it remains silent. The GTX 980 ti fan does not reach more than 50% of its capability. Very slight coil noise can be heardif the computer is very very close to you in a silent room. I am talking about an improper distance to the case itself.
Temperatures on pure idle are 30-34 between the 4 cores with a 79 F room temperatures. Under load they never exceed 65, which leaves room for light overclocking. Using OC from MSI it idles at around 40-45 and boosts up to 73 under load with the AP182 on 1/4 of the capable rpms. The 980 ti remains solid on 71-75 while playing in 1080. Reaches 78-82 in UHD with the fan under 50%.
I have ran couple of stress test with intel software and temperatures are well below any warning limit while having the OC on from MSI.
I have yet to try to manually OC the 980 ti, i dont need to do that in the near future, but i will try to when i get my hands on a 4k screen.
CPU cooler: i pondered about the L12 as well as the C12P SE14 from noctua, which are top down flow. I leaned for the D9L which blows through air out the side of the case. There is room for a push-pull setup but i find one fan able to coop pretty well combined with the AP182 on top. The cpu cooler is pretty compact and allows for beneficial air flow on the motherboard and the ram.
Feel free to contact if you want more infos.
I apologize but i did not take any pictures while building the system.
