Building the System Part II
Storage
Next up is selecting and installing a storage drive. As previously mentioned, the mounting bracket provides spaces for up to two 3.5" and three 2.5" drives. The hardware kit includes rubber washers to prevent vibration from spinning drives, and it's an unexpected and welcome extra.
The hard drives mount accross the bracket, and are held secure with four screws beneath each drive.
Up to three SSD's (or 2.5" notebook hard drives) can be installed on the other side of the bracket:
I did run into a small issue with the height of the 2.5" mounts on the bracket. A standard SATA power cable is too thick to fit squarely against the bracket, so the cable must be forced into place.
It exerts enough pressure against the drive's connector to be a concern, so I just loosened the front screws holding my SSD to alleviate this. Another work around would be to simply use some small washers as spacers below the drive. Unfortunately the included washers for the 3.5" drives were too thick to be used here.
The Finished micro-ATX Build
The case has enough room with an mATX motherboard to keep the build process relatively painless. I was worried at first about the lack of cable routing, which is especially challenging due to the storage bracket's front location (and required power and SATA cables up front). Fortunately, there's no windowed side panel here to expose an untidy build.
The placement of the PSU in particular hampers organization, even with the flat modular cables of CX750M, but it is possible to rout things around a bit.
The mini-ITX Experiment
After running some tests with the completed system it was time to try a mini-ITX build. I have to say, there’s a lot to like with the smaller form factor in this case! As I mentioned in the introduction, with mounts for an ATX power supply and the option of using a standard optical drive, the micro-ATX Colossus could be a cost-effective option for building up an mini-ITX system (even though BitFenix offers a mini-ITX version) since a builder could reuse existing parts to experiment. Additionally, the extra space gained within the enclosure with the smaller motherboard footprint allows for more flexibility with the cooling solution. There are additional cable routing options with a sizable amount of the CPU cutout exposed as well.
While either size motherboard technically allows for a top-mounted 240mm AIO cooler like the pictured Corsair H100, the smaller board made installation painless.
There is even enough clearance available to install push-pull fans if desired, while still leaving room for a multi-slot graphics card.
With either form factor motherboard, the addition of an optical drive leaves only one of the 120mm upper fan mounts available. It's up to the individual whether they can live without an optical drive just yet, but there are always external solutions.
Any chance you could append
Any chance you could append the heat results of the SLI configuration? As someone currently looking into building with this case, SLI/Crossfire thermals would have been nice to see.
That’s a good question, and I
That's a good question, and I attempted to provide GPU thermals but discarded the test data since I couldn't get anything over 80 C with the GTX 770's, single GPU or SLI. The fan just compensated to keep the temps stable right at 80 C, and I never saw anything over 82 C. It would be a different story with a less efficient blower-style cooler, and of course with any card that vents into the case – but I don't have a different pair to test right now.
Hello, great review!
I want
Hello, great review!
I want to buy the BitFenix Colossus Micro-ATX case but I think my motherboard will not fit in the case. I have a Acer dao61078lam3 mainboard (Acer Aspire X5400), they say its a Micro-ATX but as you can see on this picture below my PCI-Express slot is way up, do you think it will fit?

Your motherboard is using a
Your motherboard is using a custom design, but as long as it's within the 9.6" x 9.6" standard for mATX it will fit. Your PCI-E slot looks to be in the right place, it's just a shorter board design so you'd have a little extra space up above here. My only concern would be with the standoffs in the case, as the screw holes are in the standard locations for mITX and mATX, and you have a proprietary OEM board… My guess is that it would be fine, but I'd still buy the case from a retailer that allows returns (like Amazon) just to be on the safe side!
I am curious, did you look
I am curious, did you look into mounting a 240mm radiator on the bottom, pulling air from the bottom, fit a 120mm fan on the exhaust in the rear and a fan pulling air in from the top directly onto the gpu? Thanks I cannot figure out the most optimal air flow.
I did, and you’re right about
I did, and you’re right about the best airflow plan – but the CPU is too close to the bottom of the case due to the flipped layout to allow an easy bottom AIO mount (motherboard layout dependent, really). It’s possible with mATX, but you start running out of room quickly. I felt that the upper just made sense for a 240mm, plus there’s the removable screen up there (no filters on bottom mounts).
I think a key takeaway might be to use a blower-style GPU in this case if you’re using an AIO on the upper mount – don’t want to push the GPU heat into the rad!

Sorry I forgot to add my name for the previous comment. Hope you can get back to me. Thanks
What about a Front fan that
What about a Front fan that is an exhaust fan?
You state with mini itx and the top mounted AIO cooler but that looks to me like it would foul the graphics card.(Hoses)
And the side mounted controls could be better moved to the front, to the very edge, possibly? The lighting strip?? uh-oh, very personal choice..Finally storage.. would it really be possible;e to fit all the drives they say? 2x 3.5 and 3x 2.5? cable mgmt would be impossible wouldn’t it? I suspect 2×3.5 and one middle mounted 2.5 is all that’s practical.
Also route, rout. And Tourture, a trip on a coach to Lourdes perhaps. I use 2x Ps07 cases, looking at mini-itx next time, in perhaps 2 years.
I’ll try to answer in order
I’ll try to answer in order here –
1.) A front fan was my biggest concern when I was installing a system, since there’s no way to avoid blocking the front fan mounts when installing the PSU. It makes a lot of sense to use a front fan for exhaust or intake, but it’s not possible here unless you can mod a different PSU location.
2. Upper AIO mount isn’t a problem with the GPU because there’s enough space to go over it (big gap between GPU and side panel). Wouldn’t do upper AIO with dual-GPU though, myself.
3.) It’s possible to have 2x 3.5″ and 3x 2.5″ drives installed simultaneously, if you can use flat cables like the ones on the CX750M I installed. But even then it gets really, really messy! There was enough space to make it work up front but it looks terrible and its very hard to get to anything afterwards!
Would it be possible to
Would it be possible to install a Corsair H90 on the rear and still do a dual GPU Setup? Also, the Gigabyte Sniper M5 has slot spacing between the GPU’s. Other than the 5 expansion slots the case has, would the GPU’s still fit with the slot spacing in between?
I have the same question.
I have the same question. Because the H90 has a 140mm fan but the radiator has 170mm. That isn’t going to make it impossible to use dual GPU if we mount the water cooler on the rear?
i still can’t seem to find
i still can’t seem to find anything that breaks down the optimum air flow with this case :
can anyone let me know their thoughts on optimum airflow for this case while using the EVGA GTX 780 with an ACX cooler ?

fans-
Bitfenix Spectre Pro LED Green 120mm Case Fan * 2 for the top
another Bitfenix spectre pro(probably LED Green only 😛 ) 200 mm case fan for the bottom
p.s.
also any thoughts about the MSI N780 Lightning in comparison to the EVGA ?
or throw in the extra to get the EVGA 780ti ?
im not looking to add another card for a while anyway… so thats not an issue.
This is an amazingly detailed review! My daughter recently inherited this cool little chassis, but it is missing the 9-pin cable which makes the door buttons work 🙁
I reached out to Bitfinex but they do not have stock on a replacement part, and have refused to tell me the pin configuration so that I can just build a new cable from scratch.
I can see from your photo “3c56-colossus16.jpeg” that the order of the cables is:
white
yellow
black
orange
blue
brown
purple
red
Is there any chance you still have this chassis kicking around? And if so, would you mind letting me know which pairs lead to , , etc? I’m desperate to fix this cute little chassis up like new for my girl.
