What hard drive? It's about 4"x4"x2" tall, with no hard drive or keyboard or display, just connectors, including 3 USB. We added Ubuntu linux with a 1-wire file system (OWFS) on a $10 1 GB flash ram to handle a string of $2 Dallas sensors that respond with a 12 bit temperature after they see their factory-programmed 64-bit address go by on a single shared twisted pair. The best part is Ubuntu's bwbasic, which is almost identical to gwbasic :-) Nick
