Well heres the pictures of the upgrade as requested. The stock 500GB hard drive failed this week and the company were out of stock on the 1TB drives and everyone else was too expensive so I had to replace it with another 500GB. Got Windows 7 x64 installed and i must say its a dramatic improvement! It's absolutely rapid and opens Photoshop and Dreamweaver in a few seconds and runs alot cooler than the stock Athlon II! The fan is barely audiable and has not even run at full belt at all and the air out of the side of the unit only gets slighly warm.
