Hola
German shop Plexilaser.de is now offering new cases for the A500, made from acrylic glass.
You can get it toned smoke-grey, matte black or clear !
Additionally you can add an LED light for inside the case in various colors and, if you use an internal GOTEK drive instead of the original floppy, you can get a custom side panel that has the perfect opening for it.
One package includes an entire A500 case you gotta assemble yourself, though it's quite easy and doesn't take too long.
Prices range from 99€ for a clear case without any addons, to about 170€ including the toned pieces, LEDs and custom ventilation slots (you can pick a text, like AMIGA 500). Shipping to the US/Mexico is 20€.
