It's an ASUS 300M. A pretty high end model when I bought it 4 or 5 years ago, and as a basic PC, running a standard Linux it would be fine for at least 5 more years. But running Chrome OS, it may become a doorstop any time.
So you could go that route, if you like. I ended up doing something similar with my original Chromebook Pixel when Google stopped supporting it: I removed the write-protect screw from the motherboard, flashed a normal BIOS, and installed Linux Mint on it.
