Sure, why not. Variety in sentence structure is a good thing (as Martha Stewart might say).
One is prosaic; the other has a refreshing ring to it. The same reasoning applies to your position of "it." An argument could be made that the word order of your first sentence contains an element of surprise or anticipation. First comes it and then--wait for it--computer! Almost like a reverse anticlimax, a rhetorical term for "a descent in discourse from the significant or important to the trivial, inconsequential, etc."
Off the top of my head:
"Men, what I'm about to say to you men may come as a surprise or a shock. Be that as it may. It may also disappoint some of you as well. Regardless of your reaction to it, here goes: yadda, yadda, yadda, yadda . . .."
Instead of saying from the get go, for example,
"Men, you are all going to be transferred en masse to the Russian Front . . .,"
you kind of string them along, thus perhaps creating a bit more drama, for whatever reason.
