SIMM/DIMM Memory - Motherboard should support either standard or DDR DIMMs that contain SDRAM, DDR SDRAM, or RDRAM respectively. SIMMs is old fashioned by today's standards, so any boards that use them should be avoided.
Bus Type - Latest motherboards are not incorporating ISA bus slots, instead using one to five or more PCI local bus slots.
Processor Sockets/Slots - Mini or baby ATX is the mainly used form factor for personal computers, which can support Pentium 4-class processors, replacing the old AT form factor used mainly with the 386-class processor.
Built-in Interfaces - Motherboard should contain as many built-in standard controllers and interfaces as possible. Built-in sound card and built-in video adapters are a standard in most motherboards today.
