Lian Li have taken the (small) wraps off of a new multimedia I/O bezel for their high-end cases. The BZ-U02 has the usual USB 2.0 ports, Firewire and audio in/out, but also adds eSATA for plugging in high-speed external hard-drives.
The BZ-U02 fits into a spare 5.25-inch bay and comes with 80cm cables to reach back to whatever port headers are on your motherboard or, feasibly, out the back of your case to plug into a spare port there. A flap-down cover keeps any dust out.
Available by the end of July, the BZ-U02 is available in silver and black, and will likely fit any computer case rather than solely be useful in Lian Li's own range. It will be priced at around $30.
