My sole remaining Mac is a 13" 2012 rMBP. I primarily use it as a secondary system to my Linux desktop when I need to run stuff like MS Office and other commercial software, and as a jukebox for music and Youtube. I bought it a year or so ago for $150 with a broken screen and one dead USB port, but it functions OK as a desktop. (I've got it running two external monitors.) After I bought it I noticed that it kept thermal throttling, so I replaced the heat pipe. That helped a lot, but it still runs hot, so I installed "Macs Fan Control" to ramp up the fans and keep it cool. In looking at repair options, I've found that Apple wants $700 to repair the screen. Most local shops want to charge a hair over $500 to fix it. I expect that future OS support for this model will be dropped next year when OS 10.15 comes out. That raises the question of whether or not it is worth it to repair this thing, or just save up over the next year for a new model. I'm not made of money; I can swing a $500 repair bill with a little effort, but $1500 for a new MBP is out of reach at the moment. What should I do?
