Title says almost all of it
Specs i want:
I was gonna get a decent gpu like the rx 580 factory overclocked. Found one for 160 on amazon
Try something like this ($245, has a 6core, 12thread CPU, 16GB RAM a 500GB HDD and a 685W PSU, ready for a higher power card)
That won't work, the refurbished PC's normally don't have the connector, try a 1650 then or wait to see what the 2650 or 3050 or whatever it will be called brings to the table.
