The master computer makes you immune to Allegiance Subverters. The bridge, LS, and CQ prevent you from losing speed if the computer is destroyed by a computer virus.

I don't see the point of a shield generator on this design. The only possible reason for it is to prevent boarding, and on a combat ship the shields from just one generator will go down too quickly to matter much for that.

You may want to experiment with adding some emissive armor as well, and possibly stealth and scattering too.

Keep in mind that any organic ship you design will be considerably inferior in quality on a per ship basis to an equivalent tech level normal design. You will need a substantial numeric advantage to win, but your ships will be a lot cheaper, so you can afford to build more of them. For this reason, I would not recommend using master computers unless you are fighting a psychic opponent, as their greater cost would reduce your advantage.
