I doubt most people doing bioinformatics are doing their number crunching on the machine in their office. They're probably using a cluster that's maintained in a server room.

Keep in mind that these are workstations, not servers. They are intended to be used by an individual who, for whatever reason, has interactive applications with large compute requirements.

Most bioinformaticians don't know how to code very well in my experience. (Some yes, but the majority I have worked with, no).
