OCLP in imac mid-2011 (help me)

hi everyone

I want to buy a 2011 imac because of its 27 inch screen and its very good price

I want to buy i5 2400s version with 128gb ssd and 8gb ram and 512mb amd 6770m graphics

I use it as a second computer to watch tutorial videos, open lots of google chrome tabs and do some web programming.

Please don't tell me to buy a higher model because I don't have the money

Please guide me completely, can it be used without problems? , and I would be happy if you share any experience with me because I really need it

Is open core legacy patcher stable and without problems?

thanks to everyone
