NLX - CORRECT ANSWER NLX (new low profile extended) is an old form factor
that was designed for use in slimline desktop computers. NLX:
Uses a detachable riser card to provide expansion slots (the motherboard itself has
no expansion slots).
Allows the motherboard to slide in or out of the system case easily. Was replaced
by microATX and Mini-ITX.
BTX - CORRECT ANSWER The BTX (balanced technology extended) form
factor was designed as a replacement for the ATX form factor. However, it did not
gain widespread adoption. With BTX:
The CPU is positioned in such a way that air flow is increased.
There is no heatsink fan. Instead, a thermal module or shroud fits over the CPU to
move heat directly out of the system. The back panel orientation and mounting
location is reversed.
ATX Full-tower - CORRECT ANSWER ATX full-tower cases are the largest
computer cases. Full-tower cases have a lot of space for external and internal
components. ATX full-tower cases are compatible with the following form factors:
Standard ATX
EATX microATX
