depends on what you are planning to do with the rig.
i'd recommend linux for everything that does involve serving purposes. if you're planning to run Linux then there are virtually no restrictions on the hardware itself. All IDE HDDs run fine regardless of their size (500GB, 750GB whatever you want), all PCI devices should work (like SATA controllers) and even ISA devices are supported. there are no known issues with CPUs or RAM and power saving options (they make the cpu run very cool on idle) are available out of the box.
for old games and such i'd recommend DOS, Windows 98. with those you'll have to care about the HDD selection since they rely on the BIOS reported size of the HDDs. 128GB is max. with a patched bios. additionally there might (with DOS for sure) be lacking driver support for newer pci devices. some tools might be helpful to properly activate/configure certain cpus. power saving options might (on DOS: not sure...sorry) be used but they need special tools.
if you need a very simple workhorse i'd try a Linux that keeps a low profile. there is tons of modern configurable software that plays nice on older hardware. keep in mind that you'll have to avoid all the fancy standard stuff like KDE or GNOME. Fluxbox is a nice start but requires extensive configuration in the first place.
If you email me include [WIMSBIOS] in the subject.
