If you mean a crack along the liner running up one or the other side that would be a definite negative unless the price is very low and you e who could replace the sound board. That in itself is not expensive in terms of materials but the labor cost could be prohibitive. Figure on about $200 US for a new SB but perhaps up to $1000 labor.
If the damage from it seemingly falling over is simply cosmetic, that is not a big deal.
Sometimes though you really do find a great deal. One person I know recently bought a 40 year old Triplett Axline in excellent condition for $200; with fleece lined case, spare strings and more. She will give it feet (about $35) which the old Axlines did not have for increased stability, and as long as she is OK with blades that’s a great bargain. Those could be replaced with the smallest Truitt lever bases at a net cost of zero assuming she sells those blades.
