I would opt for a complete upgrade to a newer Mini. You have a core solo machine and it's only going to bottleneck the systems performance even with an SSD and max RAM. Don't get me wrong, a good SSD will greatly improve the performance for your machine, but I would opt for a newer Mini, then place an SSD in place of the HD, and you'll be a happy camper for a few years to come. That's just my opinion though. ;)
