Kevin: You are asking all the right questions and you can have a lot of fun, like in finding a new hobby to play with. But before spending any money, please take a look at the specs and cost of a brand new Apple Mac-Mini, or even a refurbished one, or a used one. To upgrade your tower, you can easily spend close to the cost of a new Mini. You might want to set a dollar limit, say something like $200 or $300 for software and hardware. For general info, look at http://www.lowendmac.com/index.shtml http://www.xlr8yourmac.com/ http://www.everymac.com/ http://macsales.com/ also known as OWC My thoughts to your specific questions below.

But if you say that 40 GB is enough, that suggests you do not have a lot of video or music processing to do, which further suggests that running 10.4 might be a reasonable target. Why go for 10.5 on this old machine? > > Second Processor - is it possible to add another > rather than replacing it, what could work? Second processor will not go on the existing motherboard. Replacing processor has options. Look at various vendors, including OWC. Maybe $100 - $200. > > New video card - or is the one in there fine? There are a couple features in OS 10.4 and 10.5 which will not work with the old card. But not critical for most people. > > OS upgrade - with the proper upgrades, could 10.4 or > even 10.5 be installed? 10.4 will be happy. I don't know if you can bump that machine up to the minimum requirements for 10.5. With a hack or two, you can run 10.5 below Apple's "minimum requirements." Oh, Another $50 or $80 here too. Al Poulin
