Fit 20 functions into a single 5.25" drive bay

This Sunbeam 20-in-1 panel for a standard PC slot incorporates "a Multi-Card Reader/Writer, an I/O panel, and a fan controller" with an LCD temperature monitor, along with "USB2.0, IEEE 1394 Firewire, Audio, Video, and even SATA" outputs. Pretty cool.
