We have tried to use this case in a server rack style allotment and didn't really stand up to what it needed to do so we went with a custom design. But as to why we disliked it, the case as a whole doesn't seem to like letting cool air in or hot air out. No flow through the chassis on a consistent basis. This may be in part due to the foam in the front cover that folds down. It's better for airflow down but still not as efficient as I would like and also with the foam folded down, dust and another sediment can flow into your chassis with open cases. In addition, the crossbars will limit your use of GPU's to an extent but that won't be too much of an issue for many people.

Integrated graphics, at least in my experience, never offer a sufficient hashrate and I typically stick with GPU mining. Have you tried hasing for altcoins and if so what were your speeds?

Would it be theoretically possible to offload the proof of work when mining to a miner in your rig farm while the original just does the hashing continuously to speed up mining speeds? Maybe have one miner that hashes and two that are linked to it to do the proof of  work so that the initial miner doesn't have to slow down and having 2 miners doing the proof of work will make up for it taking longer and being generally more taxing on a miner than just old school mining without proof of work. Do i sound insane or could this be something someone could actually setup?

Are you using integrated graphics?
