There was very little information on the forums about the HG Computers OSMI case. Being a SFF enthusiast i thought i'd bite the bullet and check it out.
Generally speaking the first impressions of the case are that its well done. There were a lot of little chops, cuts, dremel's, that needed to be done to fit all this stuff in and a lot of it could have been optimised for production. I found there was excess metal in places where it needn't be and it made installing the GPU impossible without small reductions.

Some of the challenges in working with this case were:
- Power button had to be replaced with one from the Orthrus. The original was too big and was clashing with the radiator.
- The motherboard had to be specific: ASUS Z370-I, due to little I/O at the top of the board, once again to help the radiator fit up there. E.g. Asrock z370 itx board wouldn't work because it has wifi antenna at the top.
- Had to use a slim 30mm ST30 radiator from Alphacool. Because the width of the case is only 18 cm and the width of the opening to fit things in the case is only about 16 cm, finding radiators that could easily go in and out of the case was a challenge. Even the slim 26mm EK had problems fitting.
- Things had to be put inside the case in the correct order: IO backplate, motherboard with CPU block/pump combo from bequiet installed, power cable, led strip, sata cables, GPU, radiator with fan (15mm only) preinstalled, power supply right at the very end.
- 25mm fan would literally touch the Silverstone SFX power supply so had to settle for 15 mm.
- Had to use custom length power cables for everything.
- Had to drill a hole in the back of the case to allow easier access to the M.2 slot under the mainboard
- Used the CPU block/pump combo from a BeQuiet 280mm AIO and some Koolance QDC fittings to make filling and draining this setup a lot easier.
- The case has one tiny flaw and that is, its so small and the ATX connector on the motherboard is so close to the front of the case that you can't actually plug in the power connector. You need to dremel out a bit for the ATX24 pin notch.

But apart from that it was a good challenge and fun to build in. And the systems hums along nicely. I'll try to post some temps later on but right now i've got it running at 5GHz.




Specs are as follows:
- Intel 8700k @ 5GHz
- 32GB GSkill 3200MHz memory
- MSI GTX 1070 ITX
- Samsung 960 Evo 1TB M.2
- Samsung 960 Evo 512GB M.2
- Samsung 850 Evo 480GB SATA
- Panasonic BluRay/DVD-Writer
- Silverstone SX650-G
- Alphacool NexXxos ST30 120mm rad
- Silverstone 120mm slim fan (will change to CoolerMaster XtraFlo 120mm slim when it comes in the post)
- Bunch of EK fittings and EK duraclear tubes
- BeQuiet 280mm AIO (used only the pump/cpu block combo from it)
- CableMod light blue cables all cut down to size
- EK blue coolant

P.S. I shamelessly stuck an EK badge over the top of HG, just because the EK one had a nicer finish to it, and i did use EK fittings and tubes in the build :)

That's really impressive! I've seen many people saying that watercooling was impossible in this case, but here you are proving them wrong.

I've been planning a build in this case for a while now. Bought my 1070 aero ITX a while ago. How's the fit of the card? Cause it's 5mm longer than adviced, but I figured it would just fit.

With a very careful selection of components it can be done.
Not all motherboards will work. Not all GPU's will work.
I tried the Gigabyte GTX 1060 in this and it did fit. But i think the 1070 variant is slightly larger therefore i dont think it will fit.
The MSI 1070 is smaller than the Gigabyte card so it works.
It literally just fits and is quite difficult to get it in the first time. However with a little practice and familiarity of angles, it can be wedged in.
You literally need to take the ram sticks out to pull the card out, that's how tight it is.
Also making a small cut in the case helps to insert it.
Also needed to make a small cut for the 8 pin connector otherwise it was just a pain to plug and unplug.

I contemplated putting in the Asetek 92mm AIO, that would fit also, but where's the fun in that ;) ..... black tubes .... yuck ;) Besides, with a 120mm radiator you can OC :)

Amazing build, was wondering where you put the pump, then realized it was embedded into the cpu block itself. Been wanting to get the osmi case, but I don't know how to get one to US.

expandable AIO, an external pump res to fill, and QDC? Mate, this is exactly the reason why I chose this AIO in the first place.
Hopefully, I'll have the time to get to do it. Great work!

Hey, I've looked into building an sff waterloop for some time, but my case (custom built and dan-case a4 size) doesn't fit a dedicated pump, and I havn't been able to get my hands on an fractal design kelvin unit, so I was wondering how you "expanded" the be quiet unit? Does the pump block have standard g¼ fitting threads?

Hey @LukeD , mind sharing your gpu temperatures? On 100% load, mine ramps up to 80C at 1800 RPM fan speed, which seems higher than most benchmarks I've seen. I'm a bit concerned what it'll do once in this case...

Ambient temp is 24 c

Idle GPU: 34 c / Idle CPU: 37 c
Idle GPU: 35 c / Max CPU: 74 c
Max GPU: 76 c / Idle CPU: 61 c
Max GPU: 76 c / Max CPU: 86 c

This is CPU running @ 4.5GHz overclock

So GPU temps seem to affect CPU temps a bit.
But i also think its because the back of the card has an exhaust and its covered by the front of the case.
I'm actually thinking about cutting a window out for it and maybe putting some black mesh there.
I think it would look good.

So you can fit a AIO (or even custom) cooled loop in that case. Just need the right mobo and also a slimmer fan. If you went with a smaller power supply (like a HD-Plex 300 watt setup) you could even probably fit the res-pump in there.

Yes, you could do something like that. I wanted to have a fully self contained unit, but a HD Plex would work very nicely here. Especially if you make a metal plate to cover the SFX PSU mounting hole.

Also I think only the Asetek 92mm AIO would fit. The 120mm AIO's now have much thicker rads. Thicker than 30 mm and those i dont think would fit.

Actually, I have two questions:

- Which one is the inlet and which is the outlet for the bequiet pump?
- When you were filling the loop using the external pump/res, do you have to fill in the same flow direction as the bequiet pump? Or it doesn't really matter?
