In the post I have seen, where the guys got a single full rack and played with it on the weekends, running it for a day added a significant amount to their bills, so yes, newer systems are more efficient (generally due to compute efficiencies), but disks are disks. Spindles are not way more efficient than before.
On the ROI part, this is a case by case issue. I for one can do the "play" part at work, too. Also, I don't want to spare space for a 1U or 2U full-depth server at home. I'm not even adding disk boxes to this. I neither have the space, nor the desire.

If you are using enterprise SSDs the you need to be aware that the JDEC standards[1] are such that the assumption for enterprise SSDs is that they are operating 24/7.
Which is why, for example, the standards specify "power off data retention" of 3 months for enterprise SSDs vs 1 year for client SSDs.
And conversely, for reliability, the standards specify "active use" 24/7 for enterprise vs 8 hours/day for client SSDs.
Like many things with ID, the choice of client vs enterprise SSDs is a 'pick two' scenario.
