  1. Start by installing the hardware for the media center PC
    1. Unpack all components and place on a flat work surface
    2. Remove the cover from the case

    3. (optional) Remove the power supply from the case to make it easier to work inside the case

    4. Take the back plate from the motherboard box and punch out any holes that are blocked so all input/output jacks are visible (caution: the metal is very thin and sharp, so be careful not to cut yourself).  Now insert the back plate into the case - this will usually require you to apply pretty equal pressure to get the back plate to seat flush into the back of the case

    5. Install the motherboard into the case, fitting all input/output jacks into the back plate and screwing the motherboard into the case

    6. Install the RAM into the motherboard - ensure that the RAM is oriented correctly and push it into place (ensure the locking tabs are snapped into the ram snugly)

    7. Install the card reader (for the APEX case the 5 1/4 inch drive bay has a flip down lid).  I installed the card reader to only one side of the 5 1/4 bay using two screws and as close to the lid as possible.  For easy of access, you should install the SDHC card prior to inserting the card reader into the case, else just insert the card by flipping down the lid at a later time.  Plug the USB cable for the card reader into the motherboard.

    8. Plug in the cases leads for power, reset, hard drive, speaker, front audio/usb, etc.

    9. Plug in the ATX power cable to the motherboard.  (optional) If the power supply was removed reinstall the power supply into the case

    10. (optional)Install a 120mm fan on the right side of the case - it will just fit between the rails of the case.

    11. Plug in the power and boot up your HTPC - assuming everything is plugged in correctly you should see the ZOTAC splash screen.  Press DEL to enter the BIOS and configure accordingly.

    12. Your HTPC build is complete!
