5 out of 5 eggsLove the case. A simple mod made me buy this over the 915f

Pros: The case is highly durable, stackable (duh, but it really works), and is easy to work in.

Honestly I don't think there is anything better or worse about this than the 915F. It is a "pick your poison" kind of thing where you get neat and easy hard drive installation and access with this case, but at the cost of clearance over the motherboard due to the rear-mount psu.

I have my improvement mods in the "other thoughts" section, which kept me from buying the 915F.

Nice drive cage.

Can take bigger radiators with some modding.

Cons: The rear mounted psu means you can't overclock (unless you have a liquid cooler or very good low-profile fan-sink. Even then, installation isn't fun when you know that upgrading means taking out the psu to get at the mobo.

There is only a 92mm front fan.

The psu is ONLY (and ONLY) supported by 4 screws. I have a fix for this though...

Other Thoughts: This is how I improved this case:

1) I painted two 2"x3" l-brackets from the hardware store black (heat resistant non-gloss coating) and installed them directly under the psu to give it support. This required some drilling, but the end-product was great, especially since the black-matte spray blends with the case.

2) I installed a 120mm fan between the hard-drive cage and mobo. This dramatically increased air-flow and improved my chipset temps.


Overall the case is wonderful. I have three identical server boxes (stacked) for different purposes. It is nice to have this system. As an IT technician it is great to have a home-friendly server rack! This case makes this a reality.

In the future, I may remove the side panels to experiment with adding a single air-cooling system via large air-ducts - similar to enterprise server rooms.

5 out of 5 eggscase

Pros: this case is Perfect for my needs, both sides come off, the top comes off and the front comes off leaving you with a bare skeleton ( Perfect for the Modder ), there is one removable 3 stack drive bay, once it is removed the inside is completely bare for you to do to as you see fit.
Each side panel can hold a maximum 360mm radiator or 2 240mm radiators

Cons: absolutely NO cons,

Other Thoughts: I am still drooling over what I'm going to cut first, The window I'm going to cut into the left side panel, or the duel drive bay opening I'm going to cut and build in the front for a Dual bay Reservoir.

I am using this with a Thermal take case, so you are not just limited to one brand of case, Measure- Measure-Measure and be ready to MOD.!!!!! to your needs
