STEP 7 Connecting the tower
Continue with the upper row, take the second pair of M4x8 screws.
Push the tower
DOWN and to the RIGHT and then tighten:
First the screw on the left
Second the screw on the right
with the M4w
Ensure all four screws are tightened properly, no wobble is allowed . Both parts
must act as one .
STEP 8 Connecting the SL1 PSU
IMPORTANT: Continue using the enclosed cardboard to have the back plated lifted
from the desk. The reason is that the power button on the PSU, which will be facing
down might get damaged.
PSU is mounted using three holes, check the first picture to see where is their
location.
Mount the PSU using three M3x18 screws. Tighten them all the way down.
Take the M3x5 screws and screw them in the back plate, 2-3x turns are enough.
We will slide a sheet in later on, so don't tighten them. Make sure each screw is
perpendicular to the back plate in both axes.
