I picked up a Mac Mini A1176 on ebay this morning for $115 minus the power adapter (good price? I managed to get a used 110W power adapter for $30, so the Mini's gonna cost me about $145 total), it's the Core 2 Duo variant, 1.83GHz, 2GB RAM, 80GB HDD, and I want to make a few upgrades on it. I heard that the Mini will "support" 4GB of RAM (with roughly 3GB usable) and I happen to have 2 2GB sticks of 667MHz PC2-5300 RAM I pulled from an old Dell laptop a few months ago. Will these RAM sticks work, or do I need special "Apple" RAM? Also, I want to replace the horribly small 80GB HDD with a 500GB Seagate Momentus 7200RPM drive (Also pulled from the same Dell laptop, but with the advantage of actually only having about 6 months of use on it before the motherboard broke). I've heard it's very tricky to get the hard drives replaced without breaking other things inside it though. Does anyone know of a good tutorial (preferably a video tutorial)? Additionally, does anyone know how I can clone the hard drive? I have an external enclosure that I can attach the new one to, but I'm not sure if I can do a sector by sector clone while running the mac off the 80GB drive? As far as I'm aware, there is no disc-install for OS X Lion, so I would have to get a Snow Leopard install disc otherwise. Not only that, but the seller I got the Mac Mini from says the optical drive is finicky at best anyway, so I'd rather not go that route if I can help it. Next would be probably the biggest, most important question: do I need any special tools to get to the hard drive and RAM slots? I've managed to crack open a few laptops without ruining them and I am quite good at replacing parts in a nice large desktop tower, but most Windows machines use regular screws and panels to access stuff and Apple is known for their difficult DIY ratings... Finally, does anyone know what sort of performance I can expect from this Mini? I realize it's a 7-year old mini computer, so it's not exactly cutting-edge, but it comes with the most up-to-date OS available to it (Lion) and will have the advantage of a 7200RPM drive with the potential for an SSD upgrade depending on the Black Friday sales this year. I just want it for general stuff, maybe to use as a media server with Plex or something, and do some mild iMovie/iPhoto stuff (Nothing major, probably not even higher than 480p for iMovie). My only prior Mac is a Power Mac G4 MDD with the entry level 867MHz dual G4 processors. I bought that about 3 years ago for dabbling in Mac OS X and it was understandably quite slow, but I'm hoping this Mac Mini will be a much smoother experience? I realize this post is long, so thanks for reading all the way through, and thanks in advance to those that can help me out!
