Spare power switch for PC case with two pin header.
We cannot verify if this will fit the front panel on your case, but it is a square housing that is quite commonly used. At worst, if replacing a faulty switch you can run this out of a gap at the front or back of the computer (not beautiful but cheaper than a new case!). Please be advised that we won't be able to advise compatibility for your computer - please look at the picture and decide yourself.
Ideal as well for testing / workshop environments where a system may be assembled outwith of a case.
