If cap is the only reason for it's fault then it would be no problem and you can do it alone with semi-good quality soldering iron but caps in most cases blow like that (when it's just one) due to fault of component BEHIND them that draw their power.
Is it SMD (Surface mounted-tiny tiny  ) of regular (a little less in size than 1.5 V AAA battery?
Anyway transistors and MOSFETs can be changed too with low cost but you are better of getting someone qualified to do it (like a electronics repair shop).

We are talking about BIG Antminer not USB version right ?

If you try to fix it yourself make sure that you use new cap with more Voltage I.E. if an old one was 1500 mF 16 V replace with 1500 mf 25 V.

P.S. If it is cap on PSU part of the machine STAY AWAY FROM IT , high voltage current is not a thing to experiment with unless you know what you are doing (If it's 330mF 250 V for example it's PSU cap for sure).They can hold dangerous voltages inside them even if you unplugged the gear , it takes days for them to be fully empty and fixing those things can lead to even more catastrophic failure.
