Easy to assemble components
In the P300 case, my setup was easy to assemble, the cable management is great and the final look is great thanks to the tempered glass.
I have to be careful when installing the power supply and the HDD brackets, you have to be careful with the Sata cables (Data/Alim) otherwise the vibrations are transferred to the whole case. If you have super quiet equipment like me, it can drive you crazy while you're looking for the cause of the vibrations xD.
