Product introduction
Comment And Reviews
Well first off with a little background, this is my first pc build in 4 years and it was very fun! specs: r5 2600, x470 tuf, 32gb vengeance pro, 500gb wd black nvme, 1tb crucial nvme sapphire nitro+ 6700xt, a 650w seasonic, and a corsair h115i 280mm. Most of these parts are from my older build in a corsair 275r case. This case is pretty beefy for a mid tower, at about a inch or so wider, 2 inches or so taller, and longer. This case has plenty of space for my gpu with about maybe 2 and a quarter inches from the front fans, and thats with a gpu length of about a foot and some change. AIO fitment is great aswell, even after installing my aio I had plenty of space to cable manage up top still aswell and space to route the 8 pin up top. As for this being the airflow version it came with 4 fans, the front 3 daisy chained together from factory, which makes cable managing so much easier, front panel has 2 usb ports, a type c, and a single combined audio jack like for some apple earbuds. The packaging is incredible, the case sleeve, the packing materials, they really made sure the case wasnt going to arrive in bad shape. In the box comes the case, and a little box, of which when opened reveals HDD cages and within those cages are more parts, the screws for the case, and the parts for the vertical mount gpu (exlcuding the riser cable). The case is really easy to build in with lots of rear cable management options, But my favorite part about this case is all the swinging panels, the glass swings out and is removable, the metal side panel swings out and is removable, the interior panel that covers most of the wiring from the front panel is removable, and the bottom swing panel also swings down for easy access to the power supply. The pcie slots are thumbscrews which made it real easy to remove, aswell as the bracker for the psu is thumbscrews, which made installing the psu very easy. The singular gripe I have about this case is the power supply shroud Personally I dont like showing off the power supply, and wish they would have included a sliding mechanism that allows you to show it off or not, or a cover. Id hope they manufacture one as a extra or start giving it in the box to new costumers, but it makes sense to have it exposed as some psu have bright LEDs and such on them, Personally not a fan but since my psu is all black except for the name on the side, ill let this slide. The airflow this case provides is really great aswell and the included fans move lots of air. TLDR very good cable management, airflow, build quality, packaging and attention to detail.
If you’re looking to top mount a fat radiator like a 280 arctic liquid freezer II and some tall RAM just buy this case, you’ll have 70mm of clearance. I got the fanless version of this case and swapped my tower cooler for the arctic liquid freezer II 280 AIO and loaded the case up with 4 arctic p14 140mm case fans. The results? My GPU temps got around 10C cooler (50f) and my CPU temps got a whopping 20C (68f) cooler. Wow! My old case wasn’t that great, my tower cooler wasn’t particularly good and the phanteks case was one of three contributors but I’m sure it made a big difference.

Why am I so sure? The G500A is an update of the P500A, the P500A has some of the coolest GPU & CPU noise normalized thermals ever recorded by the hardware review channel Gamer’s Nexus. As in, it’s both quieter and cooler than other cases. One thing to keep in mind is that one of the updates the G500A got over the P500A are the newest case fans Phanteks has to offer, the M25 fans. Phanteks claims the M25 is based on the T30-120 fan, the best 120mm fan on the market which cost $30 EACH. If Phanteks isn’t full of BS (lol) and the M25 fans in the performance version of this case are even 90% as good as the T30 fans the Performance variant of this case is an excellent deal. I didn’t know about the M25s until after I bought the fanless version of the case so I simply settled with the third best fans with the best value.

Ok, well if this case is SO GREAT why am I giving it 4 stars instead of 5? I would have preferred a front filter like the Phanteks P600S has or even compatibility for it if I wanted to buy it as an accessory. Even in this price range I’d prefer a dedicated headphone slot in the front I/O instead of the headphone/mic combo. The HDD sleds have nothing to hold the HDDs in place which is quite unusual, they just sort of lay there and hope the case doesn’t get rocked.

the bottom line is: if this is your price range and you’re water cooling your CPU get this one. For something like a Fractal Meshify 2 you’re going to have to double triple check your clearances because Fractal cases focus on air cooling. With the G500A just shove whatever you want in here man, it’ll fit bro. if you’re doing air cooling with a tower cooler consider this case’s low baseline temps since your best options besides this one for air cooling are going to be a Fractal Torrent variant that’s in your budget or the Lian Li 216. G500A offers the best GPU temps with good CPU, Lian Li 216 offers the best CPU temps with good GPU and the Fractal Torrent offers good GPU & CPU temps.
Coming from my previous case, its stupid how much air this thing moves. Not to mention its aesthetically pleasing, easy to build in, and comes with a tackle box full of extra screws. Being able to change the RGB on the case without software is great, but you cant change the brightness that way either. The mesh front panel with 140mm fans makes a huge difference in terms of airflow. Overall, its by far the best case that I’ve used and will have for a very long time.
This is a superb case. I just put together a new build with a i5-13600K and a RTX 3080 (12 GB) card. In addition, I used a 280 mm AIO (NZXT Kraken X63) on top. The slot for CPU power cable management is a little tight, but not a problem. This enclosure is very spacious, yet light and strong. It also has great airflow, combined with terrific aesthetics. However, I did upgrade the fans to Noctua products.
Lots of room in the case, great cable management, really nice looks and tons of airflow. My i7-11700kf (max 32c in it) and 6950xt run extremely cool
I would recommend this!
The case comes with great cable management, good room and mesh top and front. It also has filters you can easily pop off. Only bad thing is the top has a billion screws to undo to take off.
This case is a monster. Very beautiful and fit all my parts perfectly. I also love that the glass door opens and closes easily so I can get in and out to dust frequently. Overall a great product and I recommend this brand to anyone.
A PC case with amazing airflow, and the ability to mount a GPU vertically, away from the window to allow maximum airflow to get to the GPU.

Tames an overclocked 3080 Ti and 5800x at 5050MHz - See in game OSD pic. (Ambient Room temp 22°C)
Yes, the awesome Nochua NH-D15 Chromax fits with the window closed with high profile ram sticks.
My RAM for ref Patriot Viper Steel Series.
If you have a GPU that is taller than a reference card with the NH-D15 cooler fitted, you will not have room to fit a GPU vertically. See pictures of how much room I have with a 3080 Ti Founders Edition installed vertically.

I replaced the front fans with Corsair ML140 magnetic levitation fans, and added another one to the rear exhaust. (4 in total) These fans are connected to a fan controller, where under 40°C, the fans switch off.

I reuse two of the RGB front panel fans that were included with the case to exhaust from the roof of the case just to light up the case, and put them to use.
These fans are 4pin PWM with an extra 3pin RGB plug.

I will replace them with two ML140, once I get a lighting strip in the case, to light it up.
The included fans are OK, but they only like to run as low as 33% or higher. (You can stop the fans, if your motherboard has the option to turn fans on or off when you reach a certain temperature, like mine.)

The ML140 fans I have, can go up to 2000rpm, but due to the case not being as high quality as my previous Lian Li case, where the material used was thicker, there is a lot more vibration, which amplifies the sound these fans make.
Having a good silent fan curb, will stop this.
0-40°C = Fans off
20% 40°C to 50% 70°C
50% 70°C to 100% 90°C
MY CPU stays well under 70°C even when clocked to 5050MHz so the fans don’t peak more the 50% (1000RPM) which is a reasonable noise level.

RGB, you can either have the DRGD connected to your motherboard to control it with software, or leave it unplugged, and use the case buttons to control it. (I hate bloatware, so I use the case buttons to control it.)

Overall, I am happy with the case, was going to do a full watercooled build, but this case with the Nochua NH-D15 outright beats my old custom 360 Rad waterloop! - And my 3080 Ti is running very cool. Never expected that!
Simply beautiful case. I found it really quite easy to build in thanks to its large capacity. Not having a full size tower for years, the built in hidden cable management is a godsend for the amateur PC builder. I just wish 30X0 series GPUs weren’t so rare (at RRP, not paying some scalper) or I would have gotten that in white also!

I got an additional exhaust fan also from phanteks, as well as the cpu cooler. All together it’s quiet and keeps it’s insides lovely and cool, looks great and is very sturdy. Can’t fault it!
This is a very nice case to build a system inside of, there’s lots clever features like the ability to have your gpu vertically mounted. Lots of nice velcro straps on the rear to help cable tidy and lots of smartly placed holes so you can route your cables tidily. The airflow is really good. I bought phanteks rgb fans separately and they compliment the case really well. Coming from an aging corsair 600t its much lighter and less bulky but with more space inside, largely because there is no optical drive bays and the hard drives are smartly placed.
This case is easily the best I’ve ever built in. Everything about it is well put together. Design and production. Components just glide into place without any fuss, they screw in with zero difficulty, there’s a clever gpu anti sag bracket included, drive cages are easy to take out and put back in. And cable management is a dream. Phanteks have engineered near perfect cable management. The wires are easy to route through cut outs that never put up awkward resistance! Velcro ties that are not sealed off help speed up the tedious cable tidying considerably. You barely need to use any plastic cable ties. What an awesome case.
Comes with the usual Amazon service. I ordered, and it arrived next day. Great.
Be careful to use the right screws for the motherboard; I mistakenly used the PSU screws wondering why they only went so far in as well as wondering why only one of the extra standoffs worked in the optional micro ATX locations; until I looked at the manual inventory and saw my mistake. I now have the proper screws in place and choose one of standoff locations for my old micro ATX motherboard and it is tightly secured.

I have my system back up and running with a few minor hiccups, like securing the last RAM latch which my GPU had knocked loose, and attaching the fans to my Commander Pro fan hub that I had bought a few years ago so I could use 4-pin PWM fans with my old XPS 8500 motherboard.

Basically you need at least one of those fans running at 1400 rpm to stop the system from emergency rebooting. My GPU radiator fan had broke and the old chassis fan is incompatible with the new case at 80mm. So you need 1x 140mm at 1300-1400 rpm to drop the GPU with AIO temp from 30C to 25C idle and keep the CPU at 60C idle. When all three are running the GPU temp drops to 16-20C idle and CPU drops to 35-60C idle.

And I have ordered a new system chassis 3 pin non-PWM fan for the motherboard; a Noctua industrial 120mm 2000 rpm 3-pin fan.

And a new 4-pin GPU radiator fan (which I have mounted at the top). The ML120 fan had failed; too much dust I think caused it to fail. I needed a new case also because I had nowhere to mount the radiator; I had it free standing on felt pads and a zip tie loop as an impediment to having it stop knock against at the front of the old PC case, a nightmare really.

The radiator fan is still needed despite the cooling of the three front fans because it takes too long to cool down, like hours from when I first used them, but a dedicated radiator fan will be faster. I have opted for a Noctua 120mm industrial fan with dust resistant specs.

Getting the old antenna loose from the XPS 8500 case was too much of a hassle and I needed a tiny Philips screw driver, so I bought a cheap USB Wi-Fi adapter instead to fill in for the mini Wi-Fi PCI card. But I have since ordered an up-to-date PCI-E x1 Wi-Fi 6E card.

Considering the price of CPUs and GPUs this was the best choice; keep the old and transplant it into the new where possible and then progressively upgrade. Keep the upgrades, and when GPUs and CPUs offer good price performance per year then I buy or not I will not buy them as often.

I will look out for DDR5 and PCIE5 or 6. And a motherboard that will support a few CPU generations, at least until DDR6.


I have since installed those fans and WI-FI card. My room feels air conditioned. I was able to reduce the three front facing fans to 1000 rpm without too much noise, and I prefer them at that speed as they do circulate the air in my room and it keeps the temperature in the room nice.

I have realised after it was too late that the F12 fan is not as suited for the rear of the case as it is not made for airflow, I ordered and received the appropriate S12A fan. I did try the F12 3 pin fan just to see what it was like, it is not quite a hairdryer like I feared. But the S12A will be better. I still need to install that.

I cannot get the Bluetooth on the WI-FI card to work with the motherboard or even the Commander Pro USB headers. The legacy Dell WI-FI still lingers even if you try to uninstall it. The WI-FI 6E works well though, maximum signal strength, and eking out the most of below average speed internet (57Mb down; 19.7 up); my road is not included in the gigabit speed that other roads in my area have; there is like three high speed internet boxes near by, my road is left out, so annoying; I hope they fix that.


I installed that S12A fan in rear of the case and it quite a bit more breezy than the F12 fan was. And I got the Bluetooth working. I plugged it into the Commander Pro USB passthrough sockets, and I read some checklist of instructions to confirm that it was working. I had disabled the Dell Wireless 1703 Bluetooth device and installed Intel Bluetooth driver before though I was not sure, but I know now that the Wi-Fi card’s Bluetooth is recognized and I was able pair it with my iPhone. One mistake was disabling the RFCOMM Protocol TDI device as because of its driver date of 2006 but I re-enabled it and I think that might have helped to mitigate the problem. And a plethora of other devices or services have appear in device manager relating to the Bluetooth paired device or service.
