[DC] Could Brainiac qualify for the Orange Lantern Ring?
gpt
He collects things of all sorts for a purpose higher than mere avarice. Avarice has a component of almost irrational desire, all for the sake of having that thing (whether to stand out or to be special; that said, the thing is only special if it exists and isn't possessed by Larfleeze himself in Larfleeze's case). Brainiac collects things for the sake of knowledge and not because he wants things for primitive reasons (like rarity or appearance). He wants to learn and absorb and collect what he must to learn more and so on.

So sure, he could try it... but that would distract him from being able to run his ship and micromanage his collection efficiently and continue to do his best to absorb all knowledge. Which, in turn, would be a foil to the constant emotion of desire needed to activate the ring.
