While I wait to buy my new mac, I'm going to take on a small project to upgrade my Mac Mini. I have a few questions before I buy the parts and start on it. Any help/input is appreciated. Hard Drive Upgrade I'm seriously considering buying a HITACHI Travelstar 7K100. It is a 100GB, SATA 150 drive. (newegg link:http://www.newegg.com/Product/Product.asp?item=N82E16822146053). Any known issues with this drive? I'd like to have at least 100GB and as fast as possible so that we can browse our large iPhoto library with minimal photo load times. Memory Upgrade I'm debating upgrading to either 1.5GB or 2GB. I currently have 1GB through 2x512s. Any significant performance hits if I were to have a 1x1GB and 1x512MB, as opposed to 2x1GB? I'm not concerned about the difference in memory, but the difference in memory sizes... Processor Upgrade OK, this is the strangest part of the upgrade. I currently have a Sony VAIO VGN-SZ110, which has a 1.83GHz Core Duo. My Mini has a 1.5GHz Solo. I only do Excel, Word, and PowerPoint on the laptop, so I'm seriously considering swapping the two. (Yes, the laptop is my personal machine.) Will the performance improvement on the Mini be noticeable? We primarily use the Mini for watching DVDs, listening to music, browsing the web, browsing our iPhoto library, and soon, I will install CrossOver to run Office XP on it. Thanks in advance.
