The top / side panels come off by removing the four screws at the back of the case. Inside we find the all-black chassis and a bundle of power supply cables. I really wish more case manufacturers would paint the internals of their cases - it goes a long way in making a system much more professional looking.
The included power supply is an SFX unit rated at 450 watts and carries an 80 PLUS Bronze certification. Power connectors include a 24-pin ATX connector, 4+4 -pin CPU cable, three SATA connectors, two 4-pin Molex connectors, one floppy-style connector, one PCIe 6+2 -pin and one PCIe 6-pin connector. The number of connectors is more than adequate given the amount of hardware the chassis can physically hold.
The plastic front bezel pops off revealing a removable 120mm dust filter. The internal optical bay cover will need to be removed with a screwdriver prior to drive installation, as will the external bay cover. The back of the front bezel houses the front I/O panel connections and cables.
Let's move ahead and install some hardware in the SG05-450.
