|The Phanteks Eclipse P350X is compatible with ATX motherboards (and E-ATX motherboards measuring up to 272mm in width), which is placed vertically and thanks to the size of the case you will not run into any issues installing large heat sinks. The motherboard tray is made of solid steel, and it features a big cut out behind the socket, which allows the user to install aftermarket CPU coolers when the motherboard has already been installed. On the right side of the tray there is a plate, which allows for neat cable management. Between the motherboard tray and the right side panel there is enough space to hide plenty of cables. The case shares the latest features regarding internal layout. There is for instance is a big mid plate covering the power supply cables. In total, the Phanteks Eclipse P350X supports two 3.5" HDD and two 2.5" SSDs, both in dedicated places and well hidden.
For testing purposes we used an ASUS Z170 Pro Gaming/Aura motherboard and a huge Phanteks PH-TC14PE tower cooler and we did not run into any compatiblity issues installing the components. Building a PC based on this case is very easy and quickly done no matter whether you're using a CPU tower cooler or an all-in-one liquid cooler, but if you want to enjoy all the benefits of this case you should use an AIO water cooling setup. The space dedicated to the graphics card is large enough to accommodate even the most powerful GPUs on the market. After having put our test system together the final looks were esthetically pleasing and we like the end result.
