BTX requires up to 10 mounting holes and supports up to seven slots, depending on the
size, as shown in
Table 4.2

BTX also clearly specifies volumetric zones around the motherboard to prevent interfer-
ence from the chassis or internal components such as drives, which allows for maximum
interchangeability without physical interference or fit problems.
Withprocessorsexceeding100Winthermaloutput,aswellasvoltageregulators,mother-

to allow all the high-heat-producing core components to be mounted inline from front
to back, so that a single high-efficiency thermal module (heatsink) can cool the system.
This eliminates the need for an excessive number of fans. The thermal module includes a
heatsink for the processor, a high-efficiency fan, and a duct to direct airflow through the
