Installing Your Motherboard
NOTE: Please refer to your motherboard manufacturer’s installation procedures to
ensure proper installation of your motherboard.
1. Open your case using the procedure described on page 3.
2. If your motherboard comes with an input/output panel (the collection of ports on 
the back of your system) that is different than the panel provided by StarTech.com, 
remove the StarTech.com input/output panel by firmly pressing it from the outside 
until it pops free. Insert the new input/output panel according to the 
manufacturer’s instructions.
3. Align the motherboard so that the slots and ports on the board line up with the 
card brackets and input/output panel along the back of the computer. Make note of 
and mark the holes in the case that line up with holes in the motherboard.
4. Screw your motherboard to the holes in the case making sure you have a non-
metalic washer (not provided) between the screws and the motherboard.
5. Connect the power supply to the motherboard as directed by your motherboard 
manufacturer.
6. Attach the labeled LED connectors to your motherboard as directed by your 
motherboard manufacturer.
7. Connect your labelled USB 2.0 plugs to your motherboard according to 
motherboard manufacturer’s specifications. 
8. Attach the cables from the rear fan to your motherboard’s main fan or exhaust fan 
as indicated in your motherboard manufacturer’s manual.
Installing Your Floppy and CD Drives
NOTE: Please refer to your disk drive manufacturer’s installation procedures to ensure
proper installation of the drive.
Depending on the size of your floppy disk drive, you will install it in either the 3.5”
bays located just below the hard disk drive, or the 5.25” bays located near the top of the
case. Your CD drive will be installed in one of the 5.25” drive bays.
1. Remove the front plastic bay cover of the case.
2. Beneath the plastic bay cover will be a thin plate of metal that has been perforated 
around the edges. Remove this plate by working it back and forth until it 
completely snaps off.
3. Make sure that the green-handled floppy latch above the corresponding drive bay is
in the “Unlocked” position. When unlocked, the arrow on the drive locking 
mechanism will be lined up with the arrow beside the locked icon. (The 
locked/unlocked icons are etched onto the locking mechanism above the green tabs) 
4. Slide the disk drive into place, making sure that it is flush with the front panel of 
the computer and that the screw hole on the disk drive lines up with the hole in the 
bay.
5. Move the green-handled floppy latch into the “Locked” position to secure the drive.
NOTE: If you are going to be moving the computer case, StarTech.com recommends
securing the disk drive with a screw to prevent damage.
6. Connect your disk drive to your motherboard and power supply as directed in their 
respective installation guides.
7. Repeat Steps 1 to 6 for any other disk drives you want to install in their respective 
5.25” or 3.5” bays.
Installing a Hard Disk Drive 
NOTE: Please refer to your hard disk drive manufacturer’s installation procedures to
ensure proper installation of the drive.
The hard disk drive bracket is the smaller grey removable bracket located below the 3.5”
drive bays.

pulling the bracket away from the case. 
2. Slide your hard disk drive into the bracket, making sure that the screw holes on the 
hard disk are aligned with the circular screw holes in the bracket.
3. Screw the hard disk drive to the bracket.
4. Return the hard disk bracket to the computer case by aligning the bracket with the 
grooves in the case and gently sliding the bracket forward until it clicks.
5. Connect your hard disk drive to your motherboard and power supply as directed in 
their respective installation guides.
