Hard drives are only a few watts each, even under load. If you want to add only two more, you'll be increasing your load on the PSU by a whopping 12W or so, and Dell would never leave that little headroom in their PSU. If your PSU assplodes because of an extra 12W, then it was way past due for replacement anyway!

The only problem I had, and this may just be this particular PC, was that it wouldn't power up until I installed a PCI card, anything, as if there wasn't enough draw or something to send a signal to the PSU. I plugged in a very old PCI video card, or a Soundblaster, I can't remember, and that did the trick. It's been working like a champ ever since.
the percentage of power drawn from each rail has shifted, from the 3.3V and 5V rails to the 12V rail. Depending on the design of the regulators in the PSU, things may not work right if certain rails are unloaded. So matching an old system with a new PSU sometimes does not work.
