In the space vacated by the drive cages, Fractal has included mounting points so the area can repurposed for installing a pump and reservoir. 3.5 inch drives are mounted vertically on the right side of the case and there’s only space for three drives rather than eight on the R5. More importantly, this frees up the entire front portion of the case, allowing air to flow from up to three 140 mm fans, mostly unimpeded. On the inside, all the drive cages and 5.25 inch bays have been taken out, so the front panel no longer functions as a door. The Define S is a lower cost variant that lacks a fan controller and implements an interesting design twist. The physical dimensions are practically identical, as are the build materials. Physically, it looks just like the Define R5 with its recognizable ModuVent covers on the top of the case hiding each ceiling fan placement and numerous ventilation slits running down the sides of the front bezel. Higher level use case steps are treated as goals for the lower level.The newest model, the Define S, hopes to gain traction with both budget users and watercooling enthusiasts. Create use cases for every goal associated with a use case template and maintain the same abstraction level throughout the use case.The system’s value proposition identifies the significant role. Identify significant goals associated with each role to support the system.This includes all roles played by the users relevant to the system. For each category of users, create a user profile.Permitting a user to access the functionality of another event.Describing the basic course of actions and exceptional flow of events.

Recording scenarios from trigger events to ultimate goals.Modeling the goals of system user interactions.Boxes around the use case represent the system boundary.Ĭharacteristics associated with use cases are: To represent an actor's participation in a system, a line is drawn between the actor and the use case. Actors are represented using lines with the name of the actor written below the line. Use cases are modeled using unified modeling language and are represented by ovals containing the names of the use case. Goals: Use cases are typically initiated by a user to fulfill goals describing the activities and variants involved in attaining the goal.System: Use cases capture functional requirements that specify the intended behavior of the system.Actors: Actors are the type of users that interact with the system.There are three basic elements that make up a use case: Use cases define interactions between external actors and the system to attain particular goals.
