That seems to be the fault of the transcription, i.e. by whoever sat and read through the scroll text in order to enter it as a forum comment.
The scroll itself in the intro is in all-caps, i.e. all the text is shown as caps.
Also, I really think context makes it fantastically clear here that it's talking about aspects of computer hardware.
The "dram"? Meaning a unit of volume? : http://en.wikipedia.org/wiki/Dram_(unit)
Or did the author mean "DRAM", i.e. dynamic random access memory? Somehow I think the second meaning was intended, in which case, as an acronym, ALL CAPS is required.
