Hello

For the past weeks, I have been looking into mining altcoins. I have put together some rigs, but not really decided what to buy yet.
However, I got this old PC I had from back in the days, and I noticed it had a lot of PCIe ports. (or are they PCI?)

Anyways, I was wondering if some of you had seen something simalar before, and would know if I could attatch some R9 280X's to these PCIe ports with some raisers(with a molex power input aswell) or if it would just not work?

I am installing Ubuntu on it as I write.

If some of the old cards are in the way or it's hard to see, tell me. I'll take a new pic

Thanks for any help/answers.
