those two requirements together are unusual. most rackmount 1U systems are headless, except a basic VGA for initial configuration. dual display is generally found on a desktop system.
I agree. In this case, the floor is not the best environment for the equipment, the adjacent rack has only 1U of short-depth rack space available, and the desktop is already crowded with keyboards and monitors.
Since the reqirements are (relatively) modest (except those two), I was hoping to squeeze something in.
Looks like I'm out of luck, and buying another full tower to hold a motherboard, a disk drive, and one expansion card.

Have you considered "Desktop" type of cases? You could maybe place them bellow the existing Desktops, to conserve the horizontal space.
You can also think about Building a "beast" system that would run original CentOS and one or more guest systems (CentOS, Windows, whatever). If you use KVM Virtualization, and buy MB with "IOMMU" BIOS option (https://en.wikipedia.org/wiki/List_of_IOMMU-supporting_hardware), you could pass PCI devices (second graphics card, telemetry PCI card, etc) to guest system, thus making current systems obsolete.
So far I have only heard about IOMMU and PCI passthrough, so do not hold me to my words, but they say it works.

I've been following GPU passthrough with KVM casually for a while, testing andon stacks from EL6 up to Fedora Rawhide. Passthrough on other devices work great - you loose guest migration ability, of course - for everything *except * graphics devices. I would not consider this a viable option.

Depending on the performance requirements and what other systems might drive a display or VM, you might make something work with a VM hosting the applications and a remote X display (or 2), Freenx, NX are good for that and work cross-platform.

how about an ultrasmall form factor desktop, such as the Dell Optiplex 7010 USFF ? those have dual displayport outputs (requires $7 optional video output panel), and are 24x6.5x24cm

I was going to recommend the Optiplex 7010 as well. I run 32-bit CentOS 6.4 on about 4 dozen of these systems here at work. The price in the US is less than $800, and the dual DisplayPort outputs easily drive two 1920x1200 LCD monitors (a very common configuration here at work).
