Wanted to share my 2c as there’s a lot of negativity here for a box which isn’t bad for the price. 

Ive finished setting mine up - Vega Frontier (air). First off - the power supply is fine. Running the card at full whack whilst benchmarking showed no throttling, and with a 6-8 pin adapter it’s able to power the card (rated at 300w) perfectly. If it can power one of AMD’s power hungry monsters, it should be able to handle most cards 😉

Remember, when NVidia etc “recommend” a 650w PSU, that’s when you have a full build - cpu, hard drives, etc. The 1080ti is rated for a max of 290w (most cards), so this enclosure will power them absolutely fine. You could power a couple of hard drives, an i7 7700k and a 1080ti with room to spare on a 650w PSU. All this has to handle is 300w for the graphics card, 65w upstream power, and residual power for the ports and board. It’s plenty.

The legs are indeed idiotic. I’ve removed them, which makes the footprint smaller, and also opens up 2 rather large vents for cooling.

Talking about cooling - I’ve seen a few comments here say that the PSU fan was blowing into the box - I don’t know if they’ve changed this on later ones, or if it’s luck of the draw, but my PSU fan blows out of the back, so it’s not blowing hot air into the enclosure.

Since the FE is a blower, while I was removing the legs, I took the front cover off and flipped the front fan, so it blows cold air into the enclosure. This means there’s a clean flow of air from front to back. During benchmarking I opened the cover to check the ambient temperature inside - it was barely warm in there.

Have to say, I’m struggling to find any reasons to not recommend this box. Especially in the UK where prices for most enclosures are astronomical, this is hands down the best bang for buck out there.

My powersupply had issues with 1070 Ti, but it may have just been a bad power supply...  The seasonic focus plus has been a great replacement for me!

You are right about wattage recommendations are for a complete desktop so you need to look at what your card actually peaks out at under load.  Higher load per max wattage of power supply often is usually less efficient and produces more heat and us gamers love plenty of overhead for our large heads.

Yep, the legs are silly...  I haven't got to removing those yet, but I had to remove the plastic cover of the back to replace the replaceable powersupply because it doesn't have the same cutouts and the plastic pushes the usb c tb3 cable out leading to poor connection.  The replaceable powersupply wasn't thought out because the screw orientation requires the fan side of most power supplies to be blowing air onto the back of the graphics card instead of out of the case.  This wasn't changed, but just wasn't thought out and you wouldn't know that because you haven't attempted to replace it.

I would suggest the same for swapping fan direction with a blower.  Blower is probably best for most anyhow since most of these enclosures are small volume, poorly ventilated, or cooled.  So you did good!  I will probably do that same when I get the card I actually want.  For now just borrowing one.

This may be a better deal in other countries like the UK.  No idea.  It is indeed good for the money, but you need to be aware of the design issues with it and HP needs to clear up their marketing feature claims for it...

Any ideas on why power delivery doesn't work sometimes?

Does anyone know if removing the legs voids the warranty? And how about removing the motherboard of the Omen box to build a custom case? I'm in the UK if it helps

Hope I'm not necroing this thread. Just wanted to chime in again a couple months later, using my 6-to-8 pin adapter. No issues so far, I've used it mostly as a debugging GPU for machine learning projects. 

I never got displays to work on Ubuntu 16, but nvidia 384 driver sees it alongside my 940MX which is all I needed, and SSD, ethernet, and USB controllers work fine on the latest kernel I could get working on my Spectre, 4.13 (using DaBlitz guide). SSD auto mounts once I send authorization to the Omen, and net interface switches from wifi to ethernet with no problem.  I just switch to my Usb-C to HDMI adapter when I need to do stuff on there with my other monitors. I heard Ubuntu 17 would have better egpu display support, I'm just too lazy to switch right now. Main problem with my card and linux is lack of manual fan control, the linux nvidia driver only sees/controls 1 of the 3 EVGA icx fans, but thats probably EVGA specific. I have to hop onto windows, set fans to manual, set them all to 100%, then reboot to ubuntu, or else I'll hit 76c doing some big models. At 100% everything stays cool around 63c, even with the Omen closed.

On Windows 10 everything works including displays, obviously. A little while after I got the adapter, I ended up doing some "burn in" with long gaming sessions on external monitor, and later I took the Omen with me to travel for 2 weeks, and used the laptop display with the Omen for gaming. No issues there, it does get hot though. I use aggressive fan profile in the EVGA software so it doesn't go above 65c, this is probably not as bad with a blower card.

The Core V2 looks great, but now I'm spoiled with integrated SSD and ethernet, probably won't switch.

I am thinking of purchasing an Omen eGPU unit that is being sold online as "refurbished" and nearby for collection only (in the north of England, UK), with the intention of using it sometimes for gaming, but most of the time for when I'm not using my laptop to mine a particular coin I would like to accumulate more of (MinexCoin or MNX in case you are wondering).

I don't yet have a GPU to put in the Omen, but like the fact that I can swap this out at a later date if I wish to upgrade (or replace when it gets fried).

The last poster in this thread @bonbaun seems to of confirmed that it can be used with Ubuntu Linux (which is my preference if mining and no screen is required obviously) and I see that it is also possible to run these using older Macbooks with Thunderbolt ports (such as my old early 2011 15" Macbook Pro).

My main machine these days is a quad core i7 Dell Precision M5520 with Thunderbolt 3, so I would expect this to play nicely with the Omen Accelerator.

My questions regarding this piece of kit are:
1. Do all GPU cards fit in the thing, or are there limitations due to the (poor) internal design and power supply placement?
2. Are eGPUs restricted in their processing (and potential overclocking) potential due to the fact they are external?
3. If the Omen Accelerator also has a type-C USB port on it, would this allow you to possibly daisy chain 2 of them together?
4. Is it worth buying one "refurbished" to save approx 1/3 of the current retail price, if there is no warranty with it (I would hope it would still qualify for the manufactures warranty).

Sorry for the barrage of questions. 

If anyone wants to know more about GPU mining the MNX coin (Windows or Linux) feel free to give me a tap.  Currently if you have any MinexCoin you can "park" them in the MinexBank and be rewarded with an additional 13% after one month, while also seeing the value of the MNX steadily rise as per its design (read the whitepaper). 
And MNX cannot be mined with ASIC, so its a good one in the medium to long term...

Noob here and appreciate any guidance.

I'm having a tough time with Spectre x360 15 2017 + Omen Accelerator + EVGA 1070 Ti card. The 2 places where I'm having issue are:

- The 1070 Ti needs 8 + 8 power. I put the Accelerator 6+2 into 1 and the Accelerator 6 -> adaptor -> the other 8 pin. Is this correct?

- Even though the card's lights came on and it seems to be powering and recognized by the Spectre, I'm having a heck of a time with driver install. Windows keeps telling me "Windows has stopped this device because it has reported problems. (Code 43)" with the Problem code "0000002B". I've tried complete removal of all Nvidia software and reinstall, to no avail.

Appreciate any tips, thank you

get a 6pin to 8pin adapter
i had that problem with my 980 Ti and it was because the card acted like it was ON, but it really wasnt.

I haven't been paying much attention to the eGPU world for a while, happily running my modded Akitio TB2 with my HP Spectre X360 13" without problems, but by chance I saw today that, on the HP UK store, the Omen Accelerator is for sale at 50% off. It's currently out of stock so no idea if it's discontinued now or will return at with this deal again or at the full price. A bargain has been had so if you're interested in this eGPU I'd keep a regular eye on the HP website.

So is it possible to switch the PSU? Everybody is suggesting a seasonic. I want to switch mine because of the noise level of the PSU. It blows the heat of the PSU into the back but is there also an PSU which does it the same way?
I also wanted to know if it is possible to switch the fan in the front of the box. It´s loud too and it´s too weak in my opinion. I also can´t decide in which way it blows the air.
