  Given an arbitrary graph $\Gamma$ and non-negative integers $g_v$ for each
vertex $v$ of $\Gamma$, let $X_\Gamma$ be the Weinstein $4$-manifold obtained
by plumbing copies of $T^*\Sigma_v$ according to this graph, where $\Sigma_v$
is a surface of genus $g_v$. We compute the wrapped Fukaya category of
$X_\Gamma$ (with bulk parameters) using Legendrian surgery extending our
previous work arXiv:1502.07922 where it was assumed that $g_v=0$ for all $v$
and $\Gamma$ was a tree. The resulting algebra is recognized as the (derived)
multiplicative preprojective algebra (and its higher genus version) defined by
Crawley-Boevey and Shaw arXiv:math/0404186. Along the way, we find a smaller
model for the internal DG-algebra of Ekholm-Ng arXiv:1307.8436 associated to
$1$-handles in the Legendrian surgery presentation of Weinstein $4$-manifolds
which might be of independent interest.
