Inside the 309 Continued

Peeking at the back, and we have the last of the daisy chain EGO fans in the rear. Also, here we can get a view of the vented expansion slots, which are all internally accessible.

Flipping around to the rear, and we have the cable management area. Here we have a pair of HDD trays and, of course, the bundle of chassis cables that lead to the complex ARGB solution along with front I/O ports. Up top, we have the area we looked at previously, which allows top exhaust airflow for the preinstalled fans or fans and radiator, depending upon needs. There are not a ton of predefined cable tie-down loops, as In Win has several circular holes everywhere, which can be used with a zip tie as well.

However, even those are not plentiful, so you will have to plan out your runs if you want the nailed down cable look. If you do not care about the side you cannot see, there is plenty of space to tuck cables away, as I will show in our test build.

Here we take a quick peek at the 3.5" trays, which are removable but are not toolless. All of the Drive trays require fasteners to mount the drives, which is not a huge deal but is more work than a slide-in drive tray that vibration mounts the drive with quick-swap metal pins.

Here we have the PSU area, and as you can see, there are no pads for the PSU to rest on here. The PSU is mounted on its side up here means the PSU will lay on the metal panel above the motherboard top. It is also worth noting that the mounting location for the PSU means that your PSU fan will always be facing the fans as we see here, not the rear panel. This means that the PSU will be pulling air from the main chamber. I would like to see at least a small pad here for the PSU to rest on just to reduce potential harmonics and metal to metal contact.

The cable array due to the intricate ARGB solution is a bit more involved. This is what the front panel cabling consists of:

  • 2x SATA power connectors (Feeds LED Lighting and controller)
  • 4-pin PWM fan connector (Feeds EGO Fans)
  • 3-pin ARGB connector (Feeds motherboard sync to the ARGB controller)
  • USB 3.2 Gen 2 connector (Feeds Type-C port)
  • Power, Reset, Power LED, and HDD LED connector
  • HD Audio connector
  • USB 3.2 Gen 1 20-pin connector (Feeds 2x Type-A ports)
  • USB 2.0 10-pin "DWE" connector (Connects ARGB controller to the motherboard)

This has everything you would need to get your system up and running, including the lighting effects. One thing to note is that if you want the Glow2 Software to control the fan speeds, you will need to leave the PWM fan header removed from the motherboard; we will, however, let our motherboard control the fan speeds.
