Getting Inside the Case
Unpack the SuperMicro SC750A from the box right side down. This allows for a quick and easy removal from the box. Remove protective foam from the case. Remove the front bezel. Place one hand at the bottom of the bezel. Use your free hand to hold the case steady. Pull outwards, away from the case. The bezel should snap off. Unscrew the two single screws holding each side panel to the case. The panels will swing open to their respective sides. The panels are in hinges, and will only open up to 90°. Remove the panels from their hinges by pull the panels upwards then outwards. Inside the case will be: (1) 5.25" internal bay, (2) external 3.5" bay, (3) 90mm fan preinstalled, (4) six 5.25" external bays, (5) power supply (Optional), (6) 90mm fan preinstalled, (7) 120mm fan (optional), (8) two internal 3.5" bays, (9) three 80mm fans (optional), (10) power cord, (11) case feet preinstalled, (12) accessories box, (13) bezel/speaker leads, (14) bag of screws and mounting accessories, (15) four 80mm fan holders, (16) slot covers, (17) three 80mm fan holders (two preinstalled, see 9).
Installation of Motherboard
The SuperMicro SC750A supports ATX, Full AT, and Baby AT form factors. The most common form factor is the ATX. Make sure the stand-offs are in the right places. If not, the stand-offs will have to be moved or installed. To move a standoff, simply push in the two notches present on the sides of the standoff using tweezers. Installation of the standoff is done from the back of the motherboard tray. Push the standoff into the correct areas matching that of your motherboard. NOTE: Strong force is needed to install the stand-offs. Using a flat object to help with installation is suggested (such as the blunt end of a screw driver).
When the stand-offs match the screw hole present on your motherboard, you are ready to install the motherboard. Simply place the motherboard so the stand-offs match, and screw it in.
Fan Placement and Installation
What sets apart the SuperMicro SC750A from other ATX Tower case is the amount of fans that can be used, and the unique placement of them. There are a total of 10 bracket/mounting areas for the placement of one 120mm fan, seven 80mm fans, and two 92mm fans. Your SC750A from Directron.com will come with two 92mm fans preinstalled.
One 92mm fan is placed above the power supply unit to pull air out of the case. Another 92mm fan is placed on a mounting bracket to help cool down the CPU/Chipset area. You may however remove the mounting bracket and place it somewhere else, as desired. Just unscrew the single screw holding the mounting bracket in place.
The bracket may be moved anywhere along the middle rail, or the top rail. A cutout for an optional 120mm fan is located just below the power supply unit. The fan will be mounted directly to the case with 4 screws. There are three areas for 80mm fans to pull air into the case. These are located behind the front bezel. Install any additional fan holders if necessary. These fans are optional, however, they help aid in cooling. There are also 4 additional fan holders included with the SC750A. These optional fans can be placed near the 5.25" drive bays using the provided four fan holders.
Mounting Drives and Installation of LED/Switches
The SC750A has room for 7 5.25" bays (6 external, 1 internal) and 3 3.5" bays (1 external, 2 internal). To mount an external 3.5" drive, such as a floppy drive, you must remove the top panel. Unscrew the four screws holding the top panel down. This will give you access to 1 internal 3.5" drive bay and 1 internal 5.25" drive bay. Screw in all drives necessary and replace the top panel. To install internal 3.5" drives, such as hard drives, locate the two drive bays. The bays are removable. To install external 5.25" drives, you must first remove any front panel blocking the way. The metal panels can be screwed off, while the plastic panels must be forced out. Locate and use the four notches in the plastic panel shown in the picture to remove the panel. Screw in all necessary drives. Make sure all drives are flush with the front bezel before fully tightening the drives. To install the LEDs and switches, refer to your motherboard manual. It will give you the correct payout of the pin array. Match the leads of the case to your motherboard pins.
This concludes the installation. Enjoy your new case!
