I am such a computer builder who will customize a PC to a client's specifications. I haven't been asked to build a computer with a serial port recently, but unless it is in fact non-negotiable, the increase in the price of building such a computer seems unreasonably high for technology that is many years behind even today's low-end budget technology. As not only a computer builder but also an advisor to people who want to build their own machines, I find it very hard to sell anyone such outdated and obsolete technology, especially if it causes the price of the machine to jump significantly. If a serial port is a strict requirement, perhaps the used workstation is in fact the best option. ~Kyle -- Kyle is a droid. The whole world knows it This e-mail shows it.
