Most computer tower cases nowadays have different size and color that come with flexible front panel I/O: USB, Mic and Audio ports.
USB ports - All our cases feature at least two front (or side) USB connections, allowing you to connect a USB device directly to the case, rather than connecting it to the back of the PC.
Mic port - enable you to plug in the microphone on the front panel of the chassis.
Audio port - to plug-in the speakers so that the sound can come out from the speakers.
What is included when you buy a case? You should expect the following three things when you buy a computer case:
- Power Supply Unit (PSU) but some cases exclude the PSU.
- Power cord - use to connect the Power Supply Unit to the multiple socket outlets to supply the power to the entire computer.
- Screws and nuts - use to tighten the components that attach to the computer case such as motherboard, HDD, DVD-RW drive, display adapter, etc.
How to choose a case?
- Cost and Warranty - While compare the case prices, remember that the cost to ship a case can be substantial. Also, the warranty periods offer by the computer stores.
- The correct form factor - The ATX form factor will be ideal
- Plan for expansion - Choose a case that leaves at least one or two bays for possible later expansion such as DVD drives.
- Buy case and power supply separately, if necessary - especially if you prefer the high-end PSU.
- Add supplemental cooling fans - to minimize temperature inside the case.
- Sizes and shapes - Normal size and choose the shape that you like including the color.
