DIY (Do it Yourself) Computer chassis to Learning point as following:
1, The first appearance of material, the plate is not too thin, this is the basic factor, generally need not less than 0.4mm, otherwise easily lead to deformed.
2, You have to consider your motherboard type, common is the ATX or MATX or Mini ITX motherboard, some small case cannot be put in bigger Motherboard.
3, The design of the air-flow, enough, the cooling effect as long as perfermance of PC runing. TAC2.0 is intel standard side panels of the case to help CPU,Graphsic card for cooling.
4, The light led design: This is easily neglected, not to so blink directly in front of eyes, it according to users own needs to buy.
There are a number of other factors is according to your own needs: such asthe tower and the tower or a common enclosure or game chassis selected;front interface position (some at the top, some in front); there is noUSB3.0 interface; whether the power supply device (now popular powerset); whether it is through the side; and the inside of the case you are ordinary or blackening or red (these two points is purely appearance to look good), the need for several hard bit. Power supply is the basic design.
Another concern is the installation position of the voltage, now popular power is bottom loaded,
the advantage is:
1, it is very convenient to install and uninstall the power, not across the chassis
2, the motherboard position in the chassis, rear connection equipment more convenient
3, power dissipation form independent air duct
the not good point is:
1, a lot of power supply are designed for upper loaded power supply chassis, it may caused that the cable of power supplymay not long enough, it is best to buy a 4Pin power extension line if any.
2, some high-end radiator is not too good for install, because the motherboard position is moved to upper.
3, the power supplier can't take inside hot air, as PSU is only taking itself air flow. the fan of PSU is on bottom plate of chassis.
The following diagram is the chassis structure of the power supply:
