I'm using the BLK-202a to run a shell on this machine (a P2/233 running FreeBSD--my Apache/PHP dev machine on the home net). I can see some vital stats and shut the box down gracefully from the keypad, so I don't need a monitor on this machine.
The paint job on the bezel is (ahem) suboptimal, but I have discovered the true joy of vinyl dye, and my next bezel looks tight (I'm still coughing up the fumes from painting it earlier tonight).
The pix:

shows my 202a, my FreeBSD case badge and Blue LEDs. Can't read the screen in the resized pic, but it's politely asking me if I want to halt the machine now.
