Hey, I have had a pc with this similar case before, let me tell you that a 1050 will not fit in there. Are you ordering online or have you seen it in store? Those cases are very small and are made for office work that would generally just include typing stuff like emails. I would also like to point out you will have a hard time looking for a fitting power supply, those PCs are made to be maintained, not upgraded.
Also remember the trouble you will go through trying to make further upgrades to this, trying to get stuff to fit right.
Sorry if this is awkward I keep editing to add stuff, what would help you if money is an issue would be to put all the parts on a build on pc part picker and see the wattage with what is normally in there and then with your 1050. The walmart link doesn't give exact details so I can't do this for you, sorry.
