Hi
In PC's ground is usually connected to the box itself. To be sure ground
in the PSU's can just be connected.
I have never experienced problems with ground loops in PCs. In PC's you
have all kinds of ground loops, as the same ground is usually connected to
signal leads, power supply leads and the chassis. As long as the cables
are kept short this shouldn't cause problems.

Don't know how safe it is to use different PSU's, but I have done it with
success several times on old hardware used for testing. I can't think of
any reason you should run into trouble if ground is common, and the disks
are powered up first.
Its the common ground part that can be challeging. I'm not an expert
of PC powersupplies, but in general power supplies have a floating
ground, so if you have two of them plugged in the same AC power, you
will still not have a common ground on the DC side.
