Cooler Master HAF Stacker System Review

Introduction

The HAF Stacker from Cooler Master is a modular system made up from three components each of which can be brought together in varying combinations depending on the breadth of your needs and the depth of your pockets.  In simple terms what we have is the Stacker 935 which is a standard tower chassis combined and sold with a smaller modular ITX chassis in the form of the 915R.  Should you so desire to place a truly megalithic slab of summit seeking prolific PC on your desk you can go the full trotter and create your very own Stacker 945 which if you haven't guessed is the 935 described above combined with a further ITX module in the shape of either the 915R or the 915F.  As you might imagine, the more you add the taller your PC becomes and the higher the price climbs.  The price at the top of the page reflects that of the extended system, however the base 935 which includes a slightly modified 915R can be bought for £152.99, should you wish to add a 915F then you'll have to part with another £56.50, or £66.38 for the 915R model as a standalone unit.  Being a modular system it of course entirely possible to pair up two or even 3 of the 915 modules to create a smaller system that best suits your needs

In bringing this review together we will show you the merits of each of the individual modules in their own right and then look at the system as a whole at the end.  If you're the sort who tends to skip forward then you're going to miss an awful lot of detail in doing so, so it's worth making your way methodically through this review.

Before we move on to the technical Specification section we do need to get something off our chests.  Cooler Master have claimed to have come up with the idea of a Stacker system when one of their number hit on the concept in a break between brain storming sessions.  This may well be true, and we would never begin to doubt his artistic integrity of said individual, that said, the HAF Stacker does bear more than a passing resemblance both in form and function to a certain SR-2 Stacker build by Coolmiester, AKA Paul who also happens to be a good friend of ours here at OC3D.  Just saying, that’s all.

Nice review Tom. Personally, I think the case looks pretty dreadful and I'm not sure who CM are pitching at with their modular approach. Most of us like to change our case every few years and if this is driven by a change in mobo form factor or some other reason.... most would want a new case. This looks like a jack of all trades attempt at being everything to everyone.... and pays for it.Quote

It's not going to tickle many people's fancy with it's looks ..

.. but as someone who considers looks pretty far down on the scale of case requirements - looking mostly for adaptation, options, practicality, ease of build/'monkeying around inside' - this is one heck of a range.

(even tho I'm not a case-looks person, I know when something isn't going to appeal to others)

There's some corporate uses this stack could come in useful for, and I'm keeping that in mind for suggestions. Sometimes you see something reviewed and it has features that stick in your mind when people talk to you about if and how they can have things created for them.

Good stuff. (didn't consider the pricing at all tbh)Quote

Is it just me that thinks not being able to use a 240mm AIO in the top of the main section is nuts?

HDD's or WC in the bottom AIO in the roof, then add the extra bit on the roof if you want even more water space? I still think there should be a roof panel for the main section and AIO support basically.

I think by trying to make it appeal to everyone they have actually made it a bit half arsed.Quote

Its to encourage you to buy more bits . Also, its probably because they want to make it for custom loopers, not people who use AIOs. Every other HAF case supports a 240 AIO in the roof/front(in the case of the XB ) I think.Quote

Yeah but a roof panel should be avail so you can use the lower case. With the 240mm AIO's being so common just seems retarded to not support them straight out of the box.Quote
