There is a reason why it's cheap... I'd take a wide berth.
"This AmigaOne has an unknown hardware related problem.
It crashes shortly after boot, but I can reboot it a few times and then it runs stable for days."
Then they mention:
"It has the hardware DMA fix, and on-board ethernet and audio work fine."
But later on say:
"Edit: I forgot to mention, the on-board audio quality is not very good, so there is also an Envy sound card installed."
