Description

The Hydra II Rev. B is a custom made 6U server case for high density GPU learning/mining/rendering using 8 or 6 cards, without the unwanted air leak of open frames. Revision B adds 2 x HDMI cutouts (pass through) to the front of the case for demanding 3D applications, additional vents for improved airflow, and additional mounting hardware for 3-slot cards. This case supports eight full-length graphics cards, one ATX/Micro-ATX motherboard, and two power supplies for better power distribution. Tall 6U chassis places your cards above the MB and PSU, helping you keep the cables organized underneath and out of critical airflow paths. The front railing where the GPUs mount can be switched from 8x to 6x mounting patterns when only using 6 cards. Thick industrial quality steel offers outstanding strength to hold all your cards without flexing for safer storage and transport. This cube-like 6U server case can be easily stacked or rack mounted. Extended distance from MB to GPU allows optimal placement of your cards. You can install 6 x 120mm high RPM server fans. This is the best enclosure type for high-performance number crunching machines that generate a ton of heat. Closed cabinet provides critical active airflow management (front-to-back) to prevent hot exhaust air from circulating back into the equipment air intake. Like all Hydra server cases, this one is properly built with thick gauge steel and aluminum so nothing is flimsy and everything fits precisely. Proper 6U Case for GPU Machine Learning/Deep Learning/Mining Our goal was to create a GPU server case that makes great installation experience and thermal performance and our engineers have incorporated many ideas that our customers have voiced in their reviews. The Hydra II Rev. B is designed for proper front-to-back airflow, and all the cards are strategically placed above the motherboard and power supplies. Your components all receive a proper amount of cold air, and are able to operate at their full potential. There is no need for you to "hack" the chassis like other traditional 6U server cases. Ultimate In Heat Control You can install up to 3 x 120 mm high RPM server fans at the front of the chassis to push in cold air. Closed system allows for full airflow through your cards and power supplies for improved cooling. You can install up to 3 x 120 mm high RPM server fans at the back of the chassis to pull out hot air. Read more No Need to Hack the Chassis Aftermarket cards tend to be taller around 140 to 150 mm, and some are longer around 300 to 330 mm. Most do not have recessed power connectors and require extra room for their power connectors. Other traditional 6U cases will have your power supplies in locations that require convoluted cabling, or prevents direct airflow paths, or interfere with drive installations. The Hydra 2 has taken into account all these details to ensure everything fits, and like all Hydra server cases, this one is properly built with thick gauge steel and aluminum so nothing is flimsy and everything fits precisely. Other Features ADJUSTABLE GPU BRACKETS Easily install cards of different height, length and width. Switch from eight 2-slot to six 3-slot mounting patterns. STACKABLE / RACK MOUNTABLE Maximize your profit to space ratio using industry standard 19 inch wide server racks and rails. DUAL POWER SUPPLY Use two power supplies for improved power distribution and efficiency when just one is not enough for your cards. PSU will not interfere with your cabling or prevent direct airflow paths or interfere with drive installations. Read more Hydra II Rev.

  • Nanoxia really paid attention to detail on this one!
Great chassis for your mining rig and as a bonus it can easily double as a test-bench setup! Pros: - Comes basically fully assembled which isn't often the case with frames similar to the Hydra 1 (all you need to do is add the handles and fan grilles.) - Extremely sturdy and durable; the joints on the chassis are strongly attached leaving no shaking or random rattling parts. - The handles have padding! - For an 8 GPU frame this case is actually very compact. - Tons of grommets for clean cable routing and management options. - All necessary mounting hardware included. - Fan grilles and zip-ties to keep your cables safe. - Once you have this thing assembled, nothing is going to come apart. - Clean black powder-coated finish - Made from industrial quality steel (the handles are the only aluminum parts on this should you choose to use them) - Stackable for those who want to expand their farms. - Probably one of the most compact options for a miner with reference/blower fan cards. - Great packaging. - Nanoxia paid far more deal of attention to detail than any other manufacturer I've purchased or have seen a GPU frame from. Cons: - Not really a con as I do believe "You get what you pay for" in terms of quality, but the price may seem a bit steep for some. ... show more

  • Great mining case
I have tried many gpu mining cases looking for nirvana, and have left reviews of several. Usually, I compare them to my former favorite open air frames, but they have always come up short. I really thought Hydra 2 would be the same, but I really like this case so much better. If you are not familiar with closed systems, they can stay much cooler than open air frames. Like others have said, just make sure you are using powerful fans and to close any holes that might leak air. I am using 6 ASUS RX VEGA 64 with 6 hydra high speed fans in this case, and the entire system run nicely in the range of 68C to 72C. So do yourself a favor, none of those crappy quiet fans, please. At first my Vega 64 was overheating and I was scratching my head. Then it hit me, I was cramming 2.5 slot cards using 2 slot spacing. Triple fan GPU like Asus Rx Vega 64 are not dual slot, they are 2.5 slots. Once I figured out how to reversed the GPU mounting brackets, it supported 6 x 3 slot spacing just as advertised. SO CONVENIENT! Usually, mining cases are over priced ugly piece of metal with messy internals, not this. This is so much nicer with matte black finish and cable management. It feels really nice and is well made. Like others have said, Nanoxia really paid attention to details. I will be buying this mining case in the future. This has become my new favorite. ... show more

  • Hydra 2 - Good case, no rack mounting hardware included
This is for the Hydra 2. Good case, see other reviews and photos. Fits 8 GPUs as listed. 6 GPU configuration is achieved by reversing the internal crossbars - there are two sets of holes drilled, one set for 8 gpus on one side and one for 6 gpus on the other side. Easy to do. Note that if you want to use the pre-drilled holes for a PSU you will need a standard server PSU, as desktop PSUs such as the HX1200 - which I have - have their mounting holes in a position that doesn't line up with the holes in the case (I zip tied my PSU to the back of the case by threading very small zipties through the vent grille in the PSU; zipties included with the case). You'll also need 90 degree PCIe connectors to get the cables out of the way enough to get the lid on, unless you use flexible PCIe extension cables or something similar. The thick ones that come with a standard PSU aren't flexible enough to get out of the way for the lid. Fans aren't included so you'll need at least 3 of those - and if you're installing rear fans make sure to do that before you put the GPUs in as there's not enough wiggle room to do it afterwards. Finally, no rack ears are included, if you actually plan to rack mount it you'll need rack mounting hardware. With 6 GPUs it's heavy, not too heavy to pick up with some light effort but definitely too heavy to front mount - you'll need rails. Dropped a star because for a rack mounted case it's kind of lame that you don't get 6U rack ears. ... show more

  • This case just works (great)!
Great case! The design is discrete. Installation was easy, leaving plenty of room for cables. The cooling is effective and the closed system works well, just choose the right fans (High static pressure for the intake and a higher cfm for the exhaust). I will definitely be purchasing another!

  • Great looking case for 8 GPU nodes and that's saying a lot!
I was surprised to see that this case is so neatly packed as the package is way smaller than what I initially anticipated it would be. Kudos on the color as well - I am surprised that it looks very "cool" and less like a standard PC tower case. I do wish they could have separated the screws instead of putting all the screws in one bag! Took me about 15 minutes to assemble everything, but once assembled it is a very solid case. Nothing is flimsy and I love how everything holds up. Yes, prettiness of the case matter to some people and this case will be happy to mount 8 GPUs and just rock rock out insane mining/rendering speeds. I went with three 120 mm 1800 rpm deep silence fans because this is used in office. Temperature is great, all of my 8 GPUs get plenty of space and airflow. This case gets a lot of attention in my office, i am very happy about this case. ... show more

  • well worth the $200.00
well built with a nice finish lots of room for cables , the motherboard in front is a excellent design a reset button would be nice but not really necessary , waiting for fan splitters only had 2 ways so only 4 fans ( got 6 of the noctua nf-f12 ippc -3000 rpm fans ) but moving plenty of air , it'll be a couple day before all 6 fans are running then i'll have a better idea . i put my hot running cards in , and this design keeps them under control , summer is here and i'm finding out which cards need a case like this , i was wondering if the venting on the sides was to much but seem to be working just fine so far , love how you can adjust the gpu rails , you can get the cards as close to the fans as you like or move them back a couple inches . i'll be buying several more if the price stays where its at . good job joe ... show more
