taking a look at the other pics, i think you'll have a very hard time finding a replacement motherboard. i'm not sure if that's a standard formfactor for a motherboard? if it is simply a mATX board simply flipped 180* and mounted on the other side of the chassis, that would simplify things.

based on it using the E2180 processor, it's a socket 775 board, which a direct replacement for isn't going to be as plentiful as they once were. normally, i would check out geeks.com since they tend to stock new and refurbed older hardware, but as of august 2nd, they are shutting down.
