Nothing against Linksys, I just can't see paying them for proprietary gear when I could put something similar together with parts that are lying around (for the most part).

Reason 1: it's probably quieter than a PC (no fan, etc.)

Reason 2: your argument is the same as arguments made against the empeg. Maybe (big maybe) this Linksys product "just works" as well as the empeg does.
