You might be able to install lion on your pc you have. I have the same model, 4 GB RAM (Max), Intel Core Solo 3.00GHz, Intel GMA 950. First off, the Intel GMA 950 Graphics does great with HD video. I tried running Minecraft on it but it was very laggy. The Intel Core Solo 3.00GHz processor does great for a server, specifically speaking of a Minecraft server. I can do a lot of things on it at once. And for the 4 GB RAM, it keeps the computer running really fast and smooth. For wireless, I just use a USB WLAN adapter from eBay. It works great. Now I have 10.6.8 (Snow Leopard) running on it right now because I do not dare to mess with it any further. I like it the way it is. (What I'm about to tell you might not work. I don't know. I will reply back after I test it) To put lion you might be able to use the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] (from tonymacx86.com) to put the 10.7 install on a usb stick (You have to use a mac/hackintosh something running mac os x). Then just boot off the usb and go through the os x installer. After that you might try booting with the usb and choose the mac disk. when you get on the desktop try running the same things for after installing snow leopard (those files are in the attachments). after that try using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] - lion (also from tonymacx86.com) and install the nessary files for lion. One thing you can't do is use mountain lion because it does not support intel gma 950 graphics. As soon as i get the stuff for my other gx620, if the instructions work i will make a video tutorial.
