Could you please post a photo?
Not at this time.
You don't need photos, just desolder the old motherboard sockets & replace with round pin sockets.
De-soldering the motherboard sockets can be difficult without damaging the motherboard so I would strongly recommend someone with very good soldering.
Do not take any chances with your motherboard get a expert (strongly advice).
The FastATA already has a set of round pin sockets look carefully you can remove it, in-fact it has two sets of round pin sockets one above and one below.
