Will i need extra case fans for my build? PLEASE HELP

Just my opinion on it, reading the description at newegg it seems the case comes with 2 fans preinstalled. A 120 rear fan and 120 top fan. A bit odd that they have two exhaust fans and no intake fans, personally I'd start with a rear exhaust and front intake - then consider a top exhaust, not the other way around with a top exhaust as a priority. I would plan on adding at least a 140mm to the front. 140's tend to move pretty good air and remain quieter than 120's for the most part (there's always exceptions).

I'm not exactly sure how the front of that case gets its airflow, maybe small side vents or an opening underneath? The front panel is solid, not mesh so an led fan won't make much difference there. You probably won't hardly see it if at all. Instead I'd concentrate on a better quality fan for a place you won't see it over a flashy led one. Something like one of these.

The phanteks is pretty quiet, the 1500rpm noctua can get a bit loud at full speed (moves a ton of air), the 1200rpm version may be a bit better for noise. All will move decent air without being loud. Shouldn't really need more than one intake with the other two fans, a single 960 and a locked i5. It's not going to be a very hot system.

My case design is more open air than that one, but to give an example I'm running the stock 200mm intake and 140mm rear exhaust in my enthoo pro with 2 140mm 1500rpm noctua redux as top exhaust (which are a bit overkill). All fans are controlled by a rheostat type fan controller, all are turned down quite a bit especially the two top exhaust fans. I'm running a large air cooler for the cpu but it's a 4690k and it's overclocked to 4.6ghz along with an hd 7850 gpu (pretty warm during games). No overheating issues even gaming when the room the pc is in reaches 30c (at times 34c) which is pretty warm for ambient temps. Even with an overclocked system and hotter components in a hotter than typical room it doesn't take 6+ case fans to keep it cool. So long as there's steady airflow throughout the case you'll be fine especially with cooler components. Without running two 290x gpu's or something, my setup is a typical higher heat generating system and 4 fans are more than plenty.

That should all be fine, but I'd strongly suggest trying to fit an SSD in there.

A lot of the time a PC spends is waiting for data to arrive. Booting, opening programs, loading games.

Solid-state drives are far faster at this, and so you see <10 second boot times, and large programs opening near instantly.
