Onboard serial ports

The problem I have with shops building the equip is being certain I am
making myself understood and that I am getting what I paid for and exactly
what I paid for. I'd rather buy the components and build it myself.

Right but if you  buy your own motherboard, then you have to put it together
yourself. A lot of people aren't up to that.  And if you buy a machine or
even have one built for you in a shop, their mobos might not have an exposed
serial port or even the header block. The shop is probably buying the
cheapest mobos they can and they might not have a serial port header block.

Personally, I don't buy a server class mobo when I build. I buy a
workstation mobo with the header block and use an adapter to bring it out to
the case. It doesn't cost any extra to do that any more because I just
salvage the adapter from an old machine when I build a new one.

Another thing I'd recommend is going to a used computer store and buying a
slightly older high-end machine. The Dell workstations we buy for the
University of Wisconsin all still come with serial ports exposed on the
back. You can get a dual-core machine at the University's used computer
store for $100 and it'll run linux/orca just fine.

Before I started shopping at the University's used computer store,  I used
to shop at this place where I'd leave them a note with specifications on the
machine I wanted and they'd call me when a machine matching my specs came
in. They were always happy to do that.
