This tells me you are better off investing rather than mining. A mining rig is not something you toss to the side and not pay attention to. They are a in constant need of monitoring and cleaning.
also now is NOT the time to build a mining rig, so get that out of your head, 5-600 for an RX series card and popping 600+ on Nvidia GPU's. If you take your time gathering parts you can get good deals but it takes time right now and EVERYTHING is high. Also does your apartment have a breaker box inside, you'll need nearly 1 full circuit for power draw if you have large rig, and if not a large rig you have to watch how much other crap you have on it otherwise you'll be popping breakers.
