I am doing some consulting work for a client who is trying to replace a very out of date outbound dialing program that was set up on a pair of Pentium-era tall desktops. The requirements for these computers are simple: they need to be very inexpensive, have a case that can fit a full-length ISA card (it's enormous, one website lists the dimensions as 4" x 13"), and has a parallel port that I can plug in the security dongle. The app is considered business critical, so I want to stay away from a used PC.
At first, I thought I would simply slap together my own PC from components I found on the web. But, I can find motherboards that meet my requirements, but I cannot find a case that fits. If I try to find a case that fits, I cannot find a motherboard. I then tried to look for a vendor that could provide an all-in-one solution, but they sell cases that take 16 ISA cards, and they sell for too much money.
I should add that I'm not a hardware guy, I've always purchased my computers pre-assembled from Dell and the like. I was not that familiar with the equipment out there, and now I've oversold the client, and am stumped. Can anyone make any suggestions?
