Help me Study again Campaign

I am busy studying for web development and software development and need to do everything on a computer. The computer I was using broke down because of this loadshedding and I need to get a new one to finish my studies. Please help. I have been struggling a few months to rebuild a computer. I don't need the best of the best just good enough to run all the programming software. I have some ram and a cpu again. Now I need a lga1151, ddr4 motherboard, and a 550w psu a box to put everything in and a GPU. 

Thank you for your kindness.
