Cooling & Test Configuration
In total, you can outfit this chassis with up to four 120mm fans and three 140mm fans or a combination thereof. The mounting locations in the front and top of the case can accommodate both sizes, while the rear exhaust fan location supports 120mm fans.
The two mounting locations in the front of the case can be fitted with a variety of 120, 240, and 280mm all-in-one coolers and radiators. Depending on the length of your graphics card(s), some coolers may be limited to a single fan configuration.
Even though all-in-one coolers can be mounted in the front of the case, most can't reach the CPU socket because of the fixed-length tubing. However, these locations are ideal for mounting radiators for water-cooled graphics cards. The rear exhaust fan location behind the CPU socket area supports 120mm radiators and all-in-one coolers in single and dual fan configurations.
Cable routing is surprisingly easy thanks in large part to the 1.5"-deep cable management channel behind the motherboard tray.
According to the listed specifications, this chassis can accommodate PSUs up to 160mm (6.3"). We tested power supplies as long as 190mm (7.5") without issue but, because of the location and orientation of the hard drive rack, you may be limited to using a modular power supply.
The Phanteks Eclipse P300 can be outfitted with coolers up to 160mm (6.3") tall. We were able to install a variety of air coolers, ranging from the NZXT Havik 140 to our standard test cooler, the Cooler Master Hyper T4. Working around the CPU socket area is easy enough, but it can get a bit tight if you're installing larger dual fan coolers.

On the other hand, a case manufacturer may supply a case to hit a certain target price point ... but, as in this case, they also provided (4) additional fan mounts. So, in order for me to evaluate the viability of this case, when you choose too compare it with two other cases, both of which have (2) fans installed, I'm left typing "Eclipse P300 Case Review " in the web search window looking for a review that is relevant and comes the cases on equal footing.
Yes, out of the box testing is relevant, but w/o a standardized platform (2 intakes / 1 exhaust) for apples and apples comparisons, it doesn't tell me anything I need to know. And yes, we want more inatkes than exhaust because w/o that, the resistance from the air inlet filters will mean less air in that out. And that means not only dust carrying in dust but that dust will most likely be carried in by PSI and GFX card exhaust thru the rear case grilles.
Will most likely purchase phanteks cases from here on out.
My one and only complaint is with the power button design. It is very common for it to get stuck when pressed and cause boot errors. This is because it is elongated and if you push off center, it can catch. I have to always press it with both index and middle finger to ensure it goes down evenly. This entry level tower looks to have the same button design. Don't let that deter you though...just be aware. The MANY pros out-weigh the one con.
Also, since when is i5 a budget CPU? C'mon...
