Hello, I recommend you to buy the upgraded model of Dell's 14R Front, which is the 14R Special Edition.
The comprehensive performance is higher, and the heat dissipation system has been upgraded to double conduit heat dissipation, which has higher stability and stronger heat dissipation performance.

The heat dissipation E420 is better, but the workmanship is still Dell's, and the quality of the E420 is too inferior to that of plastic.

Lenovo, Dell's after-sales service is simply rubbish.

I'm using E420 now, this one is quite powerful, I also paid attention to Dell before, but I feel that the appearance of Xiao Hei is also prominent in hardware, since you are drawing, when you use it, you can use Xiao Hei's independent display separately to your patterning software, and you can use the integrated display for other things, and Xiao Hei is recommended.

Recommend Dell excellent quality, half of our dormitory uses Dell, half uses Lenovo, but in comparison, it is still recommended to buy Dell, Dell uses basically no problems, and there are many engineer services, I feel very relieved.

It does not come with Bluetooth, it can be externalized.
It's the same with my phone when I even have an e520, but it's good to reinstall the latest Bluetooth driver. Now there is no problem with Bluetooth even kits and passing things. You try to manually uninstall the driver and then the next latest one on the official website.
Playing games mainly depends on the graphics card.
