Basic guide as follows:
1. Unpack your motherboard and lay it on the anti-static bag it came in.
2. Install your memory, cpu and heatsink on the mobo while it's laying there all defenceless and easy to get to.
3. Unpack your case. Install the risers (standoffs)
4. Install PSU. Start thinking about where the cables need to go now, and route them accordingly. USE the massive space behind the motherboard tray that the HAF 932 offers.
5. Install the mobo and connect the front panel cables and fan power cables. Adjust the power cables as needed, remember be neat!
6. Install the hdds and sata cables for the hdds, and do the optical drive at this point as well.
7. Install the GFX card.
8. Do some final tidying in the case, make sure all the wires are ziptied and locked down where possible.
