  We analyze the low temperature structure of a supersymmetric quiver quantum
mechanics with randomized superpotential coefficients, treating them as
quenched disorder. These theories describe features of the low energy dynamics
of wrapped branes, which in large number backreact into extremal black holes.
We show that the low temperature theory, in the limit of a large number of
bifundamentals, exhibits a time reparametrization symmetry as well as a
specific heat linear in the temperature. Both these features resemble the
behavior of black hole horizons in the zero temperature limit. We demonstrate
similarities between the low temperature physics of the random quiver model and
a theory of large $N$ free fermions with random masses.
