I meant the overall construction of the Geth is very close to what you described

digital communication, synthetic muscles, reinforced skeleton, etc, it's exactly what Quarrians built, although they were meant as cheap labor and army, also Geth are not a hive mind, the more of them the smarter they are, but they do not share mind, the cooperate in order to increase efficiency, a hive mind is a collective of everyone thinking the same thing,
in the Geth you will not find it, each of the program (that is how they speak of their minds) looks at things at it's own perspective, they have the individuality of a single program for each Geth, they communicate with each other and form a consensus, if the consensus is not met, they seek for a solution,
a Hive mind decides on anything as a whole, having no individual perspective, thus not seeing possible other options to find a solution other than the common solution hive societies have, which is conquer, absorb, expand, survive.
In the Mass Effect the Geth do seem like a Hive mind for others, but Tali explained it in details, also In Mass Effect 2 Legion also explains it in further detail, there is no one geth, they are all Geth, but each can look at everything from different perspective allowing for more options at hand, you should really play those games to understand it better, or read the books
