Removing both side panels, we get a great overview of the internal layout and features within S2. Inside, there is a large, open, modular layout. The motherboard tray and design follows the standard layout and supports up to E-ATX form factor. Cut-outs are clearly visible for routing cables, and we also have grommets to create a tidy workspace.
Around the back its notable that FD has implemented a new storage bracket design which is able to house 2.5” or 3.5” storage drives. These large brackets can house up to three drives or alternatively we can make use of the two SSD brackets on the backside of the motherboard tray. All of these brackets use captive thumbscrews for easy removal.
The lower section of S2 benefits from having a full length PSU shroud with the top region adopting a ventilated steel panel. This panel can accommodate storage drive installation too. If desired, this panel can be easily removed.
To install the PSU into the slot, it’s necessary to detach the plate already attached over the cut-out – the PSU will need to be fed through this cut-out due to the space limitations on either side.
Although we’ve already covered the back section of S2, here is the internal viewpoint. Again, we have seven horizontal PCI expansion slot covers and two vertical mounted options too. All are fixed into place via thumbscrews.
Above the covers, there is a 140mm Dynamic X2 cooling fan, configured as an exhaust.
With the mounting bracket in place this again, is an internal perspective – this plate is able to house up to 3x 120/140mm fans and has a dedicated fill port for custom watercooling loops.
Located at the front of S2 we have two Dynamic X2 140mm cooling fans – these are both configured as intakes, bringing cool air into the chassis and across the system. Just like the top section, S2 is able to accommodate up to 3x 120/140mm fans at the front – later on we’ll explore the radiator options.
On the backside of the motherboard tray you’ll have noticed a small hub – this is the Nexus+ PWM fan hub. It can control up to three PWM fans and six 3-pin fans. This hub also features a CPU_fan header and dedicated pump header.
Nexus+ is powered by SATA power, which is something to bear in mind for the installation process. We’re pleased to see SATA being used over Molex since the pins on Molex can be easily displaced if not properly aligned and are much trickier to use.
