PC Cases and Power Supplies
The case is the housing for your system, it offers protection against the elements and can either hide or display the inner workings of your PC.
ATX form factor is the current standard for motherboard/case layouts. Before ATX there were AT cases which handled the early 8086-Early Pentium systems.
Cases can be bought in different sizes such as midi towers, full tower, server tower and desktop cases. However the common options are either mid tower or desk top cases. You may consider either depending on the place of use so that you can achieve better use of space.
If you are regularly inside your PC swapping things over or testing things you may want a larger case to allow you more room to get things in and out more easily and to give you extra space for additional drives.
Cases start from £10 and climb to well over £100 dependant on the materials and the rated power supply. For a typical mid tower case with a Power Supply (PSU) you should be looking at around £40min.
You can go cheaper but we would not advise you do so mainly as cheaper cases can be poorly made and are not finished correctly. As a result the case can be dangerous to carry or when installing hardware your fingers could be sliced on rough edges.
