Phanteks Eclipse P300A (PH-EC300ATG_BK01) high airflow full-metal mesh design, compact ATX Mid-tower, 120mm black case fan, Black

The p300a is a great, airflow focused, compact ATX case! I found the front mesh, tempered glass panel, buttons, etc. all to be very good quality and the case looks great. The build was fairly smooth with a few small quirks: 1) I had to remove the rear exhaust fan to seat the motherboard properly in place. The fan is almost directly on top of the rear I/O and my motherboard has a heatsink and small 40mm right there as well. Once the motherboard is fully installed, then the fan could be reinstalled without any issues. 2) The power supply space is a little tight. My power supply is 150mm long. I had to partially uninstall the HDD cage and rotate it out of the way to get the power supply in place. 3) There is one "mystery" wire that I found running from the top/front I/O to behind the hard drive cage. I thought this was a relic from the RGB controller of the standard p300 case and was tempted to cut it out of the case, but did not. Once the build was finished and powered on, I saw that there is a small, white LED light strip just under the bottom edge of the tempered glass panel. This cable supplies power to that light. 4) The front has fan mounts spaced for 120 or 140mm fans. I already had 140mm fans from my previous case. They installed fine, however, the actual cutouts for the fan blades are sized for 120mm fans and roughly 20% of the blade area for my 140mm fans was blocked. I cut the openings larger using a Dremel. This was absolutely not necessary, but made me feel better about the setup. I bought this case to replace a massive (by comparison) fractal define r4, and couldn't be happier. Much better airflow, and the system is quieter than it was in the fractal case since better airflow means the fans don't have to run as fast to cool the system.

The cost to quality fallacy gets musicians and tech nerds the most. I love how one reviewer says, "this is a good entry level case for moderate gaming". Huh? Moderate gaming? Temperature is the metric that means the most to me... you know, performance? I do intense gaming with a Ryzen 5900X and RX 6750 XT. AAA games at max settings w Ray Tracing for hours on end at 1280. I can also render to my heart's content, including Blender and StudioOne projects. I've got 4 Blender projects rendering right now on the computer I am typing this review on, and HWINFO has both the CPU and GPU at 60C. For fans I have 3 Corsair 120ML Pro and 1 Corsair 140ML pro. The CPU is cooled with a Skythe Fuma 2. Bottom line, temps are never a problem. As for other features, I like that it is relatively small for an ATX case. The side panel is made of heavy high quality glass that sits in solidly. Cable management it fine. The controls and USB interfaces are fine. Drive space is fine and easy to access from the back or by removing the front panel. The front panel is easy to remove but still sturdy when in place. PSU storage is fine with an easy to remove and clean dust filter on the bottom. No frills is the path to bang for the buck. The thing that many more expensive cases get wrong is simply restricting air flow. That's all. No magic. This case's mesh front does great at letting the air in. If I had to search for one nit-picky gripe, there is a weird little white LED light strip thing at the bottom that doesn't line up well and is distracting to the aesthetic, but I just unplugged it and you can't notice it was ever there. But it was a strange design choice.

I purchased mine at an inflated price (99usd) and I still love it. Its got great airflow and a beautiful design. I like having the half window too, who needs to stare at their drive bays and PSU? The compact design means its one of the smallest full ATX cases on the market. The case feels solid when fully put together, good luck finding another case at this price range (60usd normally) with the same level of quality. Cons: The front does not fit 140mm fans correctly. Their airflow is partly obscured by metal. 120mm is what it's made for. The top fan slot is barely high enough to clear the motherboard. Most motherboards will have the CPU power plugged in there so you might have to push down on the cables to get anything to fit. The thumb screws on the panels are slightly annoying but not as bad as others say. The drive bays have almost no access to fresh air. Just a tiny hole where they plug in from the front. I'm afraid to look at my HDD temps.

My system was previously in a Phanteks Enthoo Pro, but that case was too large albeit well made. This case is about a 1/4 the volume and actually fits on my desk. Also, this case looks really nice for the price, and it's probably one of the cleanest PC builds I've ever had. **I am happy with it. It makes for a compact and simple case so you can focus on the hardware.** Downsides: - feels cheaper (cheaper than Enthoo Series; nicer than Rosewill cases) - top USB came misaligned (had to force USB flash drive in with effort) - HDD/SSD tray is useless (PSU cables fill up that compartment; I don't need it but worth mentioning) Nice to haves: - *fits an EVGA FTW3 3080 Ti (lots of room to spare w/ three fans in front; haven't tried a rad)* - magnetic top filter - filtered PSU intake - deep wire management channel - air channel on PSU shroud (bottom front fan isn't wasted) - easy to remove front panel - good airflow / space for fans & rads on front - captured thumb screws on side panels - USB-C front IO (only 3.0)

The Phanteks P300A is a fantastic case. I built a $600 PC for a friend, and I got this case. Everything was easy to install. The airflow is really good. The case comes with a removable PSU dust filter - I know it works well because it's the same one that's in my P500A, that I've had for my PC for over a year and have cleaned twice. It also comes with a super handy cable management "crater," which provides quite a lot of free space to manage, along with some Velcro straps. The Hard drive cages were easily removable as well. Phanteks makes really excellent cases for almost any kind of build.

+Low price for a tempered glass windowed case +Standard parts fit in a standard fashion +Black color goes with everything +Convenient built-in cable ties and time-saving pre-tied front panel wires +Lack of sharp steel razor edges, sometimes found in low-price cases •Tempered glass is very slightly tinted. Reduces the ferocity of those eye-searing gamer RGB LEDs, but can make it a bit dark in there. •Side panel thumbscrews have a retaining system. You won’t lose them, but they’re slightly more fiddly than the standard bare hole and flat bracket. -PSU and cables are a very tight fit. Easier if you don’t have 3.5” hard drives, because then you can remove the drive bay in the front of the basement. -Low cost is achieved by not supplying extra fans, SSD brackets, and by having minimum front panel connectivity options. If you need them, you will spend all the money you would have saved. -Gap between the motherboard tray and the backside panel is very slim. Some wires may be pinched here, especially if you have two 2.5” SSDs powered by one cable from the PSU. But, as above, if you want to run 2 SSDs, you should look at a slightly more expensive case. -This case is not optimized for airflow, so your parts may get warmer than you would like. Make sure to update firmware and get those fan curves operating. Overall: a functional case, with some trade-offs to achieve a competitive price. If you have a short parts list, or are planning to run M.2 SSDs almost exclusively, or if you have spare case fans, this is a great choice.

This is a really good quality case for the price point. The only thing I will note is that it is on the smaller side of mid-size, so if you are getting a fairly big GPU be aware it's going to take some doing. I had to remove several PCI slots and lay the case down on it's back to fit my Red Devil Radeon 5700xt inside without bumping everything else around. I do wish cable management was a little bit more robust, but this is also my first PC build so it could be a user issue. Also, I see people complaining it didn't come with an IO shield but that comes with the motherboard? So don't worry about that.

It's almost a perfect case in my opinion. The only issue I have with it is the same as the other reviews say, the top USB ports don't work. The USB 3.0 cord plugs into the motherboard, but I can't plug anything into the ports on the top of the case. I still recommend the case as everything else was perfect. My photo shows the Phanteks Eclipse G300A on top of a LIAN LI LANCOOL 216RX for size comparison. Edit- It took some time but I got a Logitech wireless dongle to plug into the USB A, the C works without any issues, and after plugging it in/out a few time I can now use it for other USB A devices.
