It depends… What was the fault? Lightning or surge damage could have damaged the CPU besides the ports. You also may have a bad power supply. Apple also altered the 21.5 modes enough times with soldered CPU’s as well as RAM and missing PCIe slots. I honestly don’t try to remember which options are viable to each series unless I open it up to check it out. On the most part the lower end models tend to have soldered CPU’s so its possible yours is as well.
