Not really related about hardware, i just don't like being enforced features that i don't need/want of, yet i understand that there will *might* not be noticeable performance impact upon keeping/get rid of some features.

Just out of some sort of morbid curiosity, I would be interested in
knowing exactly what problem the OP is trying to correct or alleviate
here. If his storage, memory or whatever resources are stretched to the
limit, he would be better served by purchasing a newer, more powerful
machine. "You can't make a silk purse out of a sow's ear."
