If you can manage to free a small amount of space in a non raid 0 boot
partition you can do a remote install. You can also do one with the netboot cd
if your colo is willing to place a cd and reboot for you. You can do a vnc
remote install and pull everything from the internet if the box has access.

If you don't have any space that WON'T need to be formatted during the
install, you might just be out of luck unless you can get a boot cd to them.
