My old Mac died in a very unfortunate way — the GPU succombed. It was the last model with DVD drive provided and I really miss having the possiblity to play CDs. Anyway… I did some due dilligence about the costs of repair and the figure was higher that what I would have probably get for selling the resuscitated computer. So I gave up. Maybe someday I will tempt a repair by myself but… until then… I got a new MacBook.
The old one will be very useful for kernel module programming and debugging.
