We study the chain components arising from a dynamical system (X,f), with X a compact metric space, from the point of view of poset theory, considering both the case in which f is a continuous map and the general case in which no regularity assumption is made. Our main result are that, if f is continuous, we have that: - the chain components poset cannot be linearly and densely ordered; - every countable well-order with a maximum is the order type of the chain components poset of an interval map. If no regularity assumption is made, we have that: - there is a dynamical system on the interval whose chain components poset is countable and densely ordered; - any countable linearly ordered subset of the chain components poset must have a minimum element.
