Class A is for 3D fires like houses, boxes, and structures.
Class B is for 2D fires like oils and liquids.
There are other sub classes (Charlie will know about these) but we don't need to go there.

I would Recommend a CO2 Extinguisher for your computer equipment, as it will not damage it, and Class ABC dry chem as well for your standard cobustibles. Is your metal flamable (lithitium, sodium, etc) if so you need a Class D extinguisher. If it is just steel, aluminum, etc, go with a large ABC dry chemical extingusiher ( 1 10-15 lbs extinguisher for every 100 sq ft)
