Hi
As it is my first post, I'll first put my system with some images. It is my first WC setup, mounted with a Swiftech H2O-Apex Ultra 220 kit and a PA120.3


Side panel modded with a 120mm FAN blowing on the mb



The MCR-220 in the rear with the PA120.3 mounted on the modded lateral panel. Because of screws incompatibility, I had to put the center fan on the PA120.3 in a blow configuration between the radiator and the panel





The mcres in place
It was impossible to mount it as Swiftech claims in the manual because of the thik grommets



The mb mounted with HR-05 IFX and the 2 HR-09U type 2.
Note that the upside HR-09U is some displaced because of mb components interferring with it in length. However, the 8 mosfets are in tight contact.
I opted for a HR-05 IFX and 2x HR-09U type 2 (and yes, the P5B dlx could fit two of these mosfet coolers). I also removed the SB HS and replaced the thermal compound with some MX-1. I mounted the HR-05 IFX with a 80mm fan undervolted to 5v




And a full view with some work on the cabling. I was too impatient to make an effort on the SATA cables and the cables in the bottom rear part of the case. In any case, they are not on any air path
