Cooler Master Stacker 830

Cooler Master's first Stacker received huge praise from the community for an abundance of space and a wealth of options in terms of how to place components inside the case. The 830 continues these traits, but extends them with a more stylish design and additional options aimed at making this a truly enthusiast-friendly case.

While the Tai Chi is one of most massive cases that we've worked with lately, the Stacker 830 puts up a good fight. The case is extremely deep, with a total front-to-back measurement of 25½”. This is 4” longer than the Tai Chi – however, with the casters, the Thermaltake case is two feet tall - 3” taller than the Cooler Master. With the same relative size, but a significant difference in the two main dimensions, users will have to take care in selecting a unit that will fit where they intend to put their computer. Neither unit is that well suited for being on a desk, but with the flared feet, the Stacker might not look too bad.

In this shot of the front, most of the various materials that make up the case are visible. Brushed aluminum is the predominant finish, but black painted steel, gray plastic, and a slightly darker gray plastic (now black plastic on many units) are all present as well. The front mounted ports are at the top, but face forward, and unlike the X1 reviewed last month, they don't get covered up when the door is closed. The recessed area above that is actually the front handle, and slightly in front of that is where the power button is located.

The front-and-center Cooler Master logo is very nicely made - it was difficult to capture the real look of it, but this close up does a pretty good job. Overall, the fit and finish of the 830 is fantastic just like the logo. This is a stately case for the serious enthusiast just like the Tai Chi, but the approach to get to this feeling is pretty different.

The main design aspect that sets the cases apart is how complex the styling is. Where the Tai Chi is very monolithic, the new Stacker has quite a few intricacies and a whole lot of functionality. When the main door is open, some of this complexity is revealed.

Like the Tai Chi and other similar cases, the 830 has many external 5¼” bays accessible externally, but only nine as opposed to the Tai Chi's eleven. Another difference is that the covers are vented in this case, and each one has a second filter behind the metal grill as well. The covers hold themselves in place very loosely, but aluminum flaps span the height of the case to provide additional holding power.

This next shot turned out much better as a collage of three separate pictures, and serves to show how these flaps and the front ports look up close.

In this shot, we've opened the main door and left flap too, and towards the far right, the spring-loaded latch that keeps the door on its hinges is visible as well. Notice the ample spacing between ports and intricate molding of the plastic. Overall, this is one of the most unique port clusters that we've seen yet in terms of visual appeal, and although it might not appeal to everyone, its functional design is hard to criticize.

Viewed from a more perpendicular angle, the layout of the top panel is easier to get a sense of. Two more USB 2.0 ports, the de-emphasized reset switch, and HDD activity LED are present along with the blue backlit power button. Cooler Master's choice to label these elements is certainly an issue of taste, but at least the font that they used is futuristic and consistent with the theme of the case.

    Yes, you can. I'm surprised AnandTech missed that option in their review. I like mounting inverted (BTX-style) ATX motherboards because that points the HSFs on my graphics cards (I run SLI) up to help dissipate heat.

    let me rephrase that.

    Is it possible invert the motherboard on the CM Stacker by installing the tray on the left side in place of the usual right side


    By inverting the motherboard (insalling on the BTX side) it may allow for better CPU cooling sine the processor would be sitting on the bottome getting plenty of cool air and allowing hot exhaust to escape upwards.

    I believe it would depend on which CM Stacker you get. I have the original and I run my ATX motherboard inverted on the opposite side just for this reason (cooling.) Also because I have an XP-120 on the CPU and don't have to worry about clearance issues with the PSU.

    If you're going to buy a Stacker I suggest looking at the specs on all of them before deciding. If I was going to buy another one I'd get the original again. It offers the full 12 5.25" bays in the front, dual PSU's, ATX/BTX/Inverted ATX/Inverted BTX, and I think more mod potential than this new one. The reason is because it's so basic that you can just cut and add stuff wherever you want. The only thing I like about this new one is that 4x120mm fan array on the side. But if I really wanted to I could mod the side of my case for that.

    Also will a PC Power and Cooling Turbo Cool 850 or any other oversized PSU fit in to either the Thermaltake or Cooler Master?
  • chynn - Thursday, March 2, 2006 - link

    Yes, the PCP&C 850W PSU should fit in the Stacker. You might have to orient the PSU so the cables exit from the bottom side to clear the 120mm fan in the top center, but the Stacker will let you do that.

    I own the Thai-Chi, and my PC Power and Cooling 1 KW (same size as the 850) fits just fine. I heard a rumor that oversized PSU's, such as the PCP&C 850/1KW, won't fit in the CM Stacker 830. Can anyone comment on this?
  • JoshuaBuss - Thursday, February 23, 2006 - link

    I would say that as long as there's nothing protruding from the sides, top, or bottom of the PSU, it'll fit in the stacker fine... length isn't the issue, it's the sides, top, and bottom you'd have to watch carefully.

    What a tough decision it would be to choose between those two cases, both are feature rich and well though out and designed. (if price was not a concern)

    I love seeing case reviews on this site, especially considering how sparsely they are reviewed. What I would like to see are some reviews done on some cases that don't look like they came off they toy isle from the nearest Dollar General store. It would be sweet if you guys could do some reviews on the higher end offerings from Silverstone; especially the TJ07.

    oh, and Lian-Li. I remember when Coolermaster was pumping out the sweetest cases you could buy. I love simplicity and elegance, and it seems that most companies are all about gaudy flash.
