Assembly

Installing the motherboard is done by traditional means using screws and spacers. The Antec P20C is very well balanced in size, allowing for just the right amount of space above the board and enough depth so that even E-ATX motherboards have access to their own grommet covered cable routing openings. This time Antec actually does mention this fact as a selling point in their promotional material and even goes as far as to be underlining the fact that E-ATX boards could be dual CPU socket variants which would fit inside the P20C.


Adding a GPU is straight forward, the metal GPU support bracket works well to keep the unit level, with loads of space left towards the front of the chassis. Even when considering a sandwich liquid cooling scenario, users of most long GPUs will find plenty of space to fit everything. This again is thanks due to the slightly larger than usual case body.


Antec provides compact thumbscrews to use as pins for the 2.5" drives. They remind us of the first generation of Cooler Master pins, besides being somewhat larger. In comparison, the second generation has a bigger tip to keep drives in place, allowing the pins to be employed with 3.5" drives as well. That said, Antec's implementation works quite well for 2.5" drives.


To install a 3.5" drive, the easiest method is using the plastic tray. It is tool-less, you just snap the drive into place and then slide it back into the case until that tray pops into the cage securely.


There is actually plenty of room to slide the PSU into the case without even having to go through the back of the chassis. This time we tried, while we had assumed it would not fit in the DP503, which uses essentially the same body as the P20C. Having both options is a nice touch.


Adding an AIO into the ceiling of a case is always an interesting step to see how well it fits, and if it gets in the way of the motherboard at all. In the case of the Antec P20C, our 360 mm radiator fits effortlessly. There was no massaging or excessive force needed, and as you can see, the rear fan placement is still completely accessible, while the bulky motherboard cooling elements are cleared perfectly. You even have access to the connectors at the top edge of the board, although it's a bit of a squeeze.


With everything installed, the case makes a very clean impression overall, however there is the location of the GPU power routing element, which clearly favors long GPUs. Antec could have placed a second one to the left of it for shorter units. In addition to that, while all the other cable routing openings have grommets, this one lacks such an extra which is unfortunate. In the rear, the final results are good and really have potential. We were struggling a little bit with the 4-way PWM splitter cable as it provides plugs in series and as such bundling it up was a bit tricky. On top of that, we opted to route the four ARGB cables from the AIO towards the back and left the ARGB connectors accessible. The Antec P20C offers plenty of flexibility and lots of zip tie hooks, so with a bit of patience and creativity having a very clean build is absolutely achievable.

Finished Looks

Turning the system on, there is really nothing to immediately tell you that it is on besides the blue power LED. The three fans in the front are actually impressively quiet. But naturally, our testing will give us a comparable number after 30 minutes in idle for everything to warm up.


Thanks to the clear glass panel, you can also view all your hardware within nicely, while the back of the Antec P20C bears no unexpected surprises with all the connectors at the usual places.
