Inside the P120 Crystal
Here we now dig into the P120 Crystal; we removed the panel to ensure you can see the details in the chassis. You can see the vertical mount for radiators that run parallel to the motherboard. With the removal of the top-mounted 3.5" bays, you can install a 360mm here. This vertical mount is where our H100i will reside.
Taking a look at the rear, we see the slotted back I/O mounting for a 120mm fan or 140mm fan depending on what you opt to use here. As previously mentioned, the rear can also mount a 120mm radiator with a maximum length of 160mm. Here we can also see the vertical triple slot mounting for a GPU or other add-in card running adjacent to the seven main expansion slots.
The bottom of the P120 Crystal chassis has a slotted mounting for 120mm or 140mm mounting. Same as we observed previously, the slotted mounting gives a plethora of mounting options for fans or radiator mounting. You can also see that adjacent to the lower mounting, there are pass-through holes for cabling, which will be useful for the front panel and USB pin header routing.
The PSU shroud on the P120 Crystal is an interesting one. First of all, being up top is always weird in current generation chassis. The PSU shroud is a nice looking unit with a sight window so you can show off your PSU, should you have one that is good looking or worth showing off. It is worth noting that even if your PSU is not great looking, you will see it as the opening is there and cannot be covered.
This does, however, give an exciting opportunity to case-modders to make something cool up here should they choose the P120. There is a small cable pass-through hole at the extreme right edge, which can be used for passing power cables to the GPU. The opening for the PSU fan is present as well and worth noting as your PSU can now be an exhaust for your chassis as it was for so many years in the past.
The dual 3.5" HDD trays are found adjacent to the PSU shroud covering the topmost portion of the vertical cooling mounting. Should you opt for a 360mm radiator in this location, these trays will have to be removed. The removal process for these trays is from the rear cable management area.
