Droid Engineer Archive

I'm Master Artisan, Master Shipwright, Master Merchant and just picked up Novice DE. I'm wondering if the brain put into droids actually effects how a droid behaves? Does it make them more or less responsive when you give them commands?
If so that could be very cool but I don't beleive I've seen any info about that when examining a droid. That could be somewhat misleading to the user since they really don't know what their getting for their money.
I'm brand new to DE so I could just be talking jiberish.

Nope. They are only chassis components that have no effect on the droid. You cannot choose what type of brain to use.
