Twelve titanium, one glass, one lube, and one organic item gets you an oxygenated multipurpose room. You can then almost deconstruct the bioreactor to reclaim four titanium.

You could also use those slots on extra air tanks and mooch around outside your vehicle. You do only need two of them for the suit.
