Our's is this:
Intel® Atom™ N450 processor (1.66GHz)
250GB HDD
2GB DDR2 RAM
10” (1024 x 600) WSVGA LED
The usual USB, and network ports. VGA output
Thought of replacing the HDD with SSD but after taking the unit apart to take a peek,
I found that it's stuck tight with lots of double-sided tape adhesive.
I wouldn't dare open it up again because most of the plastic clips have gone brittle.
