I have a Power Mac G5 for sale.
It's got the motherboard of PCIe 2,3 GHz, but both the PSU and CPU have been upgraded with parts from QUAD 2,5 GHz version. The liquid cooling system has been replaced with air cooler from a 2,3 GHz version.

Specs:

- PowerPC 970MP 2,5 GHz Dual Core CPU
- 2 GB DDR2 RAM
- 2 gfx cards: Radeon X1600Pro and nVidia 6600LE
- 80 GB SATA hard drive
- Realtek network card

It's got MorphOS 3.19 (demo) installed. I can also install OSX 10.5 in dual boot if needed.

Here is the gallery with pictures of the machine.

I'm asking for 150 EUR plus shipping.
