My problem with Wordpress is that it is fundamentally driven by the blog format, which really just means it's governed by chronological order.  It takes a lot to organize your content in any other way other than chronologically.  And I hate that.

WordPress is good and you can do a fine website with it as well with all the extensions, but I must agree with superboyac that I don't like the chronological order and the blog format. It depends what you want to sell through your e-commerce site - with some it might not matter. I'm thinking of setting up a site as well and include tomatocart. But first I still need to still get all the basics like a domain and web hosting. Then I'll think of the rest.

Well, quite frankly, there is no cheap solution to hardware faults on that piece of machine as they are already discontinued.  Your best bet would be to look online for those who took apart their computers and sell them by pieces of parts.

Or, go directly to Apple which as you said would cost you more.  I think that the better intelligent answer to this is not to have gotten that thing in the first place. It is a very old piece of hardware which has very little to be spoken off really.

I would have to say that if you have hardware that can keep up with a 64 bit OS, then you should take the jump immediately.  There is no reason to stay with 32 if you could get better allocation with 64, that is of course talking about a lot of memory in need for a better allocation scheme. It would not matter that much if you only have 2gb of memory.  Though an earlier statement, would be misleading if taken differently, as a 64 bit can also work with 32bit drivers as they are in compatibility mode.
