In building an arcade cabinet, several types of materials are available to you. Each has its strengths and weaknesses.

Plywood
Plywood is a manufactured board composed of an odd number of thin sheets of wood glued together under pressure with grains of the successive layers at right angles. Plywood is strong, light, rigid, and resistant to splitting and warping. It can be molded into curved or irregular forms as well.
The two types commonly in use today are those made of softwood (such as pine) or hardwood (oak and birch are common types). Other material such as MDF may be substituted for the usual wood core.
MDF
MDF is basically a mixture of fine wood fibers and a binder that's pressed into plywood-like sheets. Since MDF has no "grain", it's very stable. The sheets are flat and will stay that way. And with carbide-tipped bits and blades, it machines smoothly and easily. Topping it all off, MDF is relatively inexpensive. Some drawbacks to MDF are its weight (a 4'x8' sheet will weigh ~90 lbs) and water resistance. MDF is more moisture tolerant than particleboard, but WILL swell upon contact with water.
- MDF DUST IS TOXIC! CARE SHOULD BE TAKEN TO AVOID INHALING IT. BREATHING PROTECTION IS A MUST WHEN WORKING WITH THIS MATERIAL. EFFECTS OF INHALATION ARE EXTREMELY HARMFUL TO YOUR HEALTH
MDO
MDO is a hybrid material made for outdoor applications such as sign painting. It has a core of 5 or 7-ply plywood that is manufactured using moisture resistant resins and bonding agents between the plys. Either one or both sides (faces) are coated with a thin layer of water resistant "paper" that is similar in smoothness to MDF. This product is typically more expensive than MDF, but provides all the advantages of plywood (lighter weight, more durable, better water resistance) with the same smooth, paint-ready face surface as MDF. MDO can typically be purchased at the "big box" stores at the order desk, or usually can be found in stock in a woodworkers supply store or through a local lumberyard.

OSB
OSB is an engineered structural wood panel made up of three layers of oriented wood flakes. It is a sheet material in which strands of wood are bonded together with a synthetic resin adhesive. The alignment of the wood strands contributes to the boards strength and structural performance.
Particle Board
Particle board (sometimes called chipboard) is a composite material manufactured from wood particles (wood chips, shavings, or even saw dust) and a synthetic resin or binder, which is pressed and extruded. Particle board is an engineered-wood product and is very dense, heavy, and flat. It is used as a cheaper and less durable substitute for solid wood or plywood. It is very prone to expansion due to moisture.
