4 out of 5 eggsGreat for the price, but small annoyances

Pros: 8 drive slots and a power supply for about 100 bucks in an accommodating case, can't really beat that. Chassis feels solid, nothing about the metal parts feels "cheap". Very simple and absolutely satisfactory, is what it says it is.

Cons: Just small things: 1. You'll need molex -> SATA power adapters if you want to actually use those 8 drive slots, seeing as the included power supply only has 2 SATA power plugs. 2. The small metal risers for the motherboard are pre-installed to accommodate ATX but if you've got an mATX like me you'll discover that they're near impossible to screw/unscrew from the chassis, likely due to poor threading. 3. Included power cable is comically short for your standard home setup.

Other Thoughts: The acrylic window has a paper coating on the inside that I think you're meant to remove, but I haven't because I kind of like the way it diffuses the status LEDs...
