Micro and mini cases, as you have seen, don't fit standard sized parts but the reverse is not true--all your components will fit in a mid- or fulll-sized case. It's not much more work to put everything in a different case than it is to replace the power supply in the same case, especially a small cramped one.   

People are throwing out 486's and sometimes PENTIUMS all over the place. I've picked up a couple at the dump. OLne of them a working P200.
