Lian Li PC-B71
With its single large main compartment it was very easy to fit our test system leaving the kit plenty of room for airflow. We purposely choose the Nexus HOC-9000 heatsink as it is quite difficult to fit in many cases. The B71 has a secondary hard drive cage right above the motherboard, but the Nexus cooler has about 2mm of clearance so it was tight but it squeezed in. The only other issue was with our full length PSU as the cut in the motherboard tray for cables was completely concealed. If you want an anally tidy cable install then you will have to break out the dremel.
The hard drives are cooled by two 140mm fans, the fans swing open on a lockable door, which would be handy for an office environment where security may be needed but I can't really see the need for a home PC, I'm sure I'd lose the keys myself! The fans have a switch inside where you can select low, medium or high fan speeds. I have had a look about for exact speeds but nothing is available. The best I can do is low is silent, medium is pretty quiet with a reasonable amount of air, and high is more than bare-able with good air movement that should help keep even the hottest system cool. The hard drive cage has many ventilation holes, and with my hand as the most sensitive flow meter available was easy to feel the fans airflow on all settings on the back side of the cage. The Lian Li flow design is far more free flowing the the Corsair 800D hot swap system.
With our multi card system successfully installed with ease, I think it's time to move on to see how the case performs.
