Nope.
I needed an A4k mobo desparately the last time I purchased off him, cost wasn't my immediate concern. He sells heaps of A4000 stuff because he acquired these off some film studio or something IIRC. He is a double-edged sword... you can get great product, but expensively, but reliably. Or you can non-working "unstable" product, hefty price, but reliable.
