Recently my Powerbook's logic board died, crashed, whatever... it doesn't work anymore and I was quoted a rather large sum of money to replace it, at the same speed of a G4 at 1GHz. That didn't seem worth it to me. I was intending to hold off on replacing it till the end of this year as speed really wasn't an issue with it, it worked very well. However now it doesn't at all. I had my eye on a penryn-based system, probably a MBP... and I still do, I just decided I need an interim computer to hold me over, and I don't necessarily need a laptop right now, so a Mac mini looks to be the best bet, from a cost point of view. I had worried that 1.66GHz was kinda crap, being the lowest clock frequency currently offered, but I have heard it is more the adequate for what I need (basic stuff, no gaming, e-mail's, web browsing, word and pages documents, music, photos etc...). I know it's a bad time to buy seeing as updated are rumoured to be just around the corner, but due to my files not being readily accessible to me right now, I need a computer fast. This windows computer that is owned by my mum is alright, and I may consider running windows on my Mac mini, but I want to be back on a mac, with all my files and what not. So I have a few questions for everyone, this isn't just a rant, hehe. I figure I'd want to upgrade the default offering of RAM as RAM is always good and I was used to 1GB in my PB. However I am trying to spend as little as I can. I want to upgrade the machine myself, I think I am fairly competent and have seen movies and how-to's online. I read a review that said having both RAM chips the same size only gives about a 4% speed-up, so can I install a 1GB chip and a 256MB chip ? I had heard somewhere that they had to both be the same but I don't know now. That's the first thing. Secondly I want to upgrade the HDD. I had thought of transplanting my HDD from my PB, but have decided not to for whatever reason. Like the RAM, I think I can get a HDD cheaper if I buy it myself, so the question is, if I buy a new HDD and install it in the chasis, when I turn on my mac, what happens, as it's a blank drive ? Can I insert my Tiger disk and it'll install the system for me just like that ? The optical drive doesn't worry me so I wont bother doing anything with that, every thing else should be sweet. If anyone can help me out with those queries and offer some insight, advice, etc... I'd be really grateful. Thanks.
