I haven't built a PC in years, but this case is the easiest thing in the world to open and close. I added my graphic card, hooked everything up and it's worked perfectly with my MacBook Pro (2018) on macOS Mojave. I use it for editing video and it definitely helps. The boost you get depends on 1) the application's use of the eGPU and 2) the power of the GPU you select. When it comes to the latter, spend more = get more.

Want to have a gaming laptop but not have to carry around a brick ton that doesn't fit anywhere and isn't convenient? This is it chief, you throw in a 2080ti and your small laptop becomes a gaming machine sitting on a desk. Take the same laptop and use it around the house, work and school and keep it with you. Desktop replacement requires desktop technologies like this. It's worth it.

I wish it had provisions for a hard drive, but still really well built and easy to use.

Good quality, all-metal workmanship, good heat dissipation and low noise.

This is a great external gpu. I used this on an old dell with a paired monitor and this thing works so well. I currently use it with my rtx 2060 and it handles it no problem. 100+ FPS on games. Great bang for the buck.
