Inside the SST-SG09B
As I started to remove the top panel along with the full right side and about half of the left panel, it required removing the thumbscrews in the back, but I also had to remove the screw that was in the middle of the left side to get the panels to come off.
To remove the lower section there is a screw located under the case that needs to be removed. With it gone you can see the internal layout is not typical at all. I do like that there is plenty of cabling, and it is neat and tidy for transit. As for the hardware and instructions, they are shipped outside of the case.
At the top of the chassis, in front of the AP fan is the one and only optical bay. For the SG09 you will need a slot load type, as the front bezel will not allow for drawer operation.
Under the optical bay is where the PSU is to be installed. You can either use the front grill for fresh air intake into the PSU or you can flip the unit around and use the PSU to help exhaust the chassis.
Under the power supply there is a bit of excess space. Here is a good place to tie up some of the extra wiring from the front I/O, and you can also see the mounting plate for an 80mm fan to be mounted to the other side of.
Just behind the optical bay is the AP 180mm fan.
The motherboard tray comes with seven of the risers pre-installed and send an eighth in the hardware bag for Micro-ATX motherboards. You can also see that the access hole in the tray is as large as it possibly can be and still have risers in the right spot.
In the back of the chassis hangs a 120mm fan above the four expansion slots. To offer a bit more room, these slots are even with the rear of the chassis and you need to remove the external cover to gain access to the screws.
Behind the tray there is a 3.5" HDD rack across the access hole capable of housing two drives. At the bottom are plastic supports to mount 2.5" drives in. Each side can hold two drives, so you can stash four 2.5" drives back here as well.
This shot was to show two things. One is that the 2.5" drive rack holds the drives stacked on each other, and the second is that by letting the drives reside here, there is plenty of room for wiring, and it keeps some of the heat out of the main compartment.
The wiring in the SG09 contains the other end of the PSU extender that was mounted to the rear of the case, has Native USB 3.0 and HD Audio. It also has a rainbow of wires for the front panel connections, but without a window to even see them, it's fine this way.
