Club Overclocker posted a review on the Cooler Master AMMO 533 case

Getting together with a group of your best gaming buddies can sure be a lot of fun. But the process of actually hauling all of your gear around can be enough to make the whole thing more pain than pleasure. LCD monitors have helped to lighten the load to some degree, being small and much lighter than the big brother CRT. So, what do we do with our PC now? We could build it in a smaller case, but that restricts the combinations of hardware you can install. Not everyone can afford building a second computer for the sole purpose of LAN parties. Yes, there are strap systems that have been devised which will wrap your enclosure in a mess of vinyl and hooks which gives you something of a handle or shoulder sling to carry the CPU with. Beyond the fact that they aren't the most convenient thing to put together, I've even had one of those strap contraptions come apart on me! The results of that were catastrophic enough that I won't trust another strap system -- ever. So, where does that leave me? Making three or more trips from the truck to the computer rooms as I pack and unpack for the party.
