Lenovo Thinkpad T420

It's a really nice notebook, one of the most used and famous from the Thinkpad series and the last one from Lenovo to keep a few IBM characteristics such as the keyboard.
It's sturdy and reliable, the specs on it are nice to run everything you want for daily use, it can handle IDEs for coding, it has great Linux Compatibility, I've been running Linux Mint 18 on mine for about 3 years now.
The only problem I've had with it is the bezel had a small crack and I really can't tell when this happened, I've just noticed it one day, besides that it heats up a bit when trying to play games, even simple ones like Visual Novels, but besides that I have zero issues with this, I've upgraded the RAM to 6Gb and it had a small improvement, maybe for the next step I'll put a SSD on it.
