Case purchased individually, on taste and color... it is Important to understand that the motherboard has a form factor, the graphics card is long and the CPU cooler is the height, and all that included. The buildings are very dolisie, there must be any hardware.

2) game WD RE or Black. As reliable HDD with a warranty of 5 years. RE - NAS system 24/7.
SSD - the Samsung SSD 850 PRO Series 256GB.

This Assembly is valid until 2020 for FullHD and games. If you intend to work with multithreaded applications, i.e. not only games, you can look at a new product from AMD.
If you wait, you can look at the 6 cores from Intel and platform 2066. More likely to take 6 cores / 12 threads. For games i7 is quite tolerant.
