Close-up (blurry):

This unit had a botched cs4231a chip replacement, with several pads missing and misaligned, as well as the usual IDE header issues. I had previously written it off as a
goner for spare parts.
But with the recent Hijack kernels, a cs4231a chip is no longer necessary. So I grabbed a Dremel tool and cut the chip free from it's pins, and then took copper braid and a soldering iron and cleaned up the pads (much better than the picture makes it appear).
It's working very well now!
