2 out of 5 eggsGood concept, lacks attention to specs or details

Pros: Good looking 3U rackmount case

Cons: Motherboard standoffs are 0.5" tall, not the regular 0.25" tall, thereby eliminating compatibility with 3U heatsinks and almost all video cards.

Motherboard standoffs are not removable and will short out a 2011 ATX MB unless cut off.

Dust filter is impossible to remove and clean without taking most of the case and computer apart.

Other Thoughts: Athena Power took a good idea and ruined it by cheaping out.

4 out of 5 eggsHeavy Duty Chassis

Pros: The case material is very heavy duty compared to most other manufacturer's chassis'. The front bezel is made of heavy guage aluminum and very strong. The extra screws provided turned out to be a godsend, as some of the screws installed from mfg were stripped.

Cons: While the overall case is excellent, the finishing leaves something to be desired. The 5.25" drive bay assembly had to be trimmed to route cables around the ATX motherboard. The fan power distribution board supplied to power up to five fans was nice, but mounted where it interfered with the mounting of the motherboard. I had to remove it and grind out the stand-offs. The drive mounting (both 5.25" and 3.5/2.5" both leave a lot to be desired, but work. Some re-engineering here would be prudent.

The stand=offs for the ATX motherboard were missing one on the front left (all relative to the front bezel) and the middle one on the left side was .75" to far to the left. Had to grind this one off because it was shorting pathways under the motherboard.

Other Thoughts: This is not a case for a beginner. If you do not have extensive assembly experience and know how to do proper modifications you will be VERY frustrated. I have been assembling servers for years and this was by far the most difficult built done. Cable routing was extremely difficult.

I would recommend replacing the supplied PS with a completely modular one to eliminate the unnecessary cables taking up the valuable footage inside the case.

Overall this product supplies what it says and will stand up to life on the road (using this as the heart of a digital mobile recording setup).
