For $W=XYZ$,
$$
V=|YZ|^2+|XZ|^2+|XY|^2.
$$
The <F-flatness> equations require at least two of $X,Y,Z$ to vanish. The <vacuum moduli space of a supersymmetric gauge theory>[vacuum space] is therefore the union of the three coordinate axes in $\mathbb C^3$,
$$
\boxed{\{Y=Z=0\}\cup\{X=Z=0\}\cup\{X=Y=0\}},
$$
and every point on it has zero vacuum energy.
