Hey guys I finally stepped out of my comfort zone and uploaded a video where I talk about the first upgrades which I have done on my most favourite Macintosh system so far. The Mac Pro 2009 4,1 The upgrades are not much. But perhaps they may give someone an idea on what they could do possibly and how, especially the Bluetooth Antenna upgrade, which I now find really priceless Here's the vid: https://www.youtube.com/watch?v=k_iTk65njmI I hope you won't find it too boring! I'm usually more energetic when I speak. It's only that I'm pretty nervous when I know that video will be published and watched by strangers and I'm sure this fear will diminish over time + English is not really my first language More upgrades to come in the future I hope!
