Machines would have no reproduction so they should have the AI Workshop type facility at the start.

They would have no need for life support or crew quarters. Therefore a Master Computer component should be made available from the start. This would make ALL of their ships vulnerable to computer viruses which will help offset their many advantages.

They should be able to get a neural net type component early. Training is simply downloading the latest combat protocols. Perhaps have the training happen either very quickly or instantly but have the experience cap lower than that of normal training centers.

Radioactives would be much more valuable since their entire population would need energy to operate. Their organics requirements would be either very low or none at all.

Colonization components would require many radioactives since new colonies would need a large store of energy to keep the population online in the early stages.

Solar Collectors to generate radioactives would be a good tech for them to have early on.

Thier effeciency and lack of physical needs would allow them to utilize planets very effeciently. Therefore they would have a lot more available space on their planets than most other species.

Machines are not known for inventiveness so research capability would suffer. Espionage however would be good due to advanced database hacking technology. Perhaps giving them a seperate set of intel projects centered around computer overrides and digital database infiltration.

They would not have to be emotionless, but of course they would all be mechanoids. Unless you want to put cyborgs in this category.

Too bad there isnt a Non-Breather trait. Machines can typically operate in any atmosphere without consequence.

Well, thats all I can think of right now.
