Hi Geeks, For this build, the GIGABYTE N170N GAMING 5 was a good choice if you consider the onboard features , size, socket, warranty and design but it's hard to make a decision on which one is best without spending over 250 peanut. I am not planning to overclock my cpu so i got an Intel Core i5-6500 3.20GHz 6MB LGA1151 and changed the included fan with a liquid cooling CORSAIR H60 and yes you can fit this fan in a 1151. The 200mm fan included with the case has been replaced by the Corsair liquid cooling fan and i have also added another Corsair 120mm (LED and Quiet Edition) on the back to produce more cold air to the cpu and also to put some lights, the air intake is connected to the sys_fan motherboard using a splitter due to the limitation on this motherboard offering only ONE system_fan so if you plan to add more fan you need to use whether a splitter or psu molex wire. The GPU fit perfectly in the Thermaltake core v1 and is also a good choice for gaming. RAM and SSH installed in less than 3minutes. This case can support any PSU size so i have opted for a EVGA 750 B2 which is semi modular , quiet but heavy. Build completed in 2hours. Running with no issues.
