I would probably do it about the same way. I bought my hardware mostly from Gateways in So. Installed the network myself, and had the Dentrix dealer install the software. I have done a lot of stuff myself, so I can understand it. I still need lots of outside help.
Computers are complicated.
I am fortunate to live in a very computer savvy area about an hour from Silicon Valley. I can hire technical people to do my bidding, and I control what they do and how much they get paid. The old one was a dinosaur. Will need to look into getting more storage for CDR soon. My 1GB slave drive will be filled up soon.
