Well, yeah, it all ends up as heat eventually.  Most of the energy going
into a hard drive ends up as heat in the chips & resistors, the rest in the
spinning platters.  Friction will cause them to stop eventually, more heat.
Stop building server rooms, you're speeding up the heat death of the
Universe.

Some people get smart and use the 'waste' heat from the server room to warm
the rest of the office.  It's not really 'free' heat as you've already paid
for it, but at least it's not wasted by being pumped out the window to melt
the snow off some trees.  I use my PC as a heated footstool, same concept.
Not in summer though.

The most efficient device you have would be your electric kettle.  Its sole
purpose in life is to turn electricity into heat, and it does that very
well.  It would be 100% efficient except you lose a little bit in the cable,
but never mind.  Plonk a Stirling engine on top to capture the waste heat,
it can power your coffee grinder.
