This is my first custom PC build which was initially for audio production but recently upgraded the graphics from a MSI 960 GTX to a Hydro GFX 980TI so that I could also use for video editing and also gaming.
My first concern when upgrading my graphics card is I wanted a AIO liquid cooled GPU as I work in hot enviroment for long periods, so I needed a case that would support 2 radiators (240mm & 120mm).
So I did some research and was at 2 minds between the 2 modular cases; Corsair 400c or Phanteks P400. Eventually picking corsair as the P400 support for dual radiators wasn't very compatiable whilst the 400c would support both radiators and still allowed me to keep all my hard drives in my build (The NZXT H440 was also another option however I'd lose to many hard drive bays due to radiators).
As you can see from the pictures I was able to fit the radiators with enough clearance to install 2 dual 120mm fans at the top. (140mm fans wouldn't fit with the cables routed through the top such as CPU connecter)
I had custom sleeved cables for my build to make cable management easier as the case with standard cables might of been a tighter fit I believe (also choosen for better aesthetics). I didn't have much trouble routing the cables in the small PSU slot.
I also have RGB LED lights installed around the case controlled by a remote controller, which was just enough room at the front (under radiator) to fit the power block and reciever. (may of crammed some loose cabling into the unsed hard drive slot).
The PSU shroud, I found quite difficult at times. Main issue was getting it to slot back in place against the bottom MOBO cables (Also routed the lighting strip underneath the shroud). However I do like as it hides the PSU and untidied cables.
And finally the acrylic window is very nice. Wouldn't recommend the case if your build is bare as its a very open view so your case might end up looking empty. Easy to open the panel and very satisfying locking mechanism. Be warned it does attract dust so needs to be cleaned reguarly.
