I have always avoided commercially manufactured computers. I am at present using a machine built by a local shop. We discussed my requirement thoroughly before deciding on a spec. I have no trial software or unneeded software. No dedicated software either. I have always had a full installation disk supplied. I would settle for nothing less. The shop is about 1 mile from my home in the unlikely event of any problems. No premium rate phone calls and waiting in a queue.
Having said all that, I hope you enjoy your purchase.
