We compute the facets of the effective cones of divisors on the blow-up of P3 in up to five lines in general position. We prove that up to six lines these threefolds are weak Fano and hence Mori Dream Spaces.

We compute the facets of the effective cones of divisors on the blow-up of P3 in up to five lines in general position. We prove that up to six lines these threefolds are weak Fano and hence Mori Dream Spaces.
