Vacation & waiting
So back from vacation and in the meantime I´ve sold the 16GB of DDR3 RAM over ebay and an old HD5770. This is a tiny step to refinance the new machine. I have found a new SM951 (AHCI Version!) m.2 SSD on an israeli online dealer and a Broadcom BCM943602cs 802.11ac Wifi + Bluetooth 4.0 PCIe extension card by a chinese ebay dealer. Both parts are on delivery and will complete my build. So, I´m still waiting (shipping is ca. 4 weeks in total).
In my vacation, I´ll complete my cutting and painting on the G5 case and with a little bit luck, I can build in the mainboard and do the fitting of the power supply.
