Rating: 5/5 HOLY COW! June 18, 2019 Ok, so to start off it is HUGE. It's a fair bit bigger than I thought it would be, BUT I love it. I decided to ditch my 2009 Mac Pro and go to a 2018 MBP, but needed a boost for graphics when working at home and this fit the bill perfectly. When ever possible I buy from OWC, you know the products will work and you know they stand behind everything they sell. This was no exception and it really helped out with graphics (working and gaming).

Rating: 5/5 Quiet, good ventilation, user friendly December 4, 2018 Perfect for my needs, I'm using a 2018 Mac Mini with the provided graphics card in this bundle, a Radeon™ RX 580 Gaming 8G. After setting up the GPU in the enclosure and plugging into an external monitor, it was good to go! Only thing that was a downside was that the GPU's software is intended only for Windows and Linux OS and there was no actual way of finding that out until purchasing the bundle, nonetheless it is not necessary to work with the enclosure. I am very satisfied with my purchase, it's hard to beat OWC's three year warranty!

Rating: 5/5 Simple install, super quiet, works great September 29, 2018 I bought the Helios "kit" with Radeon RX 580. I'm not a gamer, but wanted more performance when batch processing photographs using my Macbook Pro 13" 2018. I tested the performance of a few machines doing image exports (using PhaseOne CaptureOne pro software) with hardware accleration turned on and off. (See image).

The 13" Macbook more than tripled export performance (from 22 to 76 images per minute) when the eGPU was used (second and third rows in the chart). The nice thing is the ability to swap out the RX 580 for a better card in the future.

Also, it's very quiet, surprisingly so. At one point in the test I got a lot of fan noise but it was from the Macbook itself rather than the eGPU.

Rating: 5/5 Ready, set, go. April 18, 2018 To support the demanding graphics apps on my MacBook Pro 15, I needed a way to add a high-end graphics capability to it that was super easy to do. I had considered a few options but always favor it when OWC offers it. The card I picked was the Radeon Vega Frontier Edition Air with 16GB of memory. The installation took less than 5 minutes and as soon as I connected it to the laptop (obviously running MaxOS 10.13.4), it worked. Super easy, super quiet, and super fast.
