It's funny, when we put together the revised testbeds, the Zotac GeForce GTS 450 Eco was chosen because it employed a single-slot cooler and would be indicative of the kind of video card most HTPCs would use. Yet many modern Mini-ITX cases (and even comparatively old standards like the SG05) include two expansion slots. The solution? Test the case with the GTS 450 and our standard ATX testbed card, the ASUS GeForce GTX 560 Ti! That's exactly what I've done here with the SilverStone Sugo SG05.
CPU temperatures are still pretty solid and consistent with the SG05, even when we include the GTX 560 Ti with its 170-watt TDP. Note that idle thermals actually increase a little with the GTS 450; I suspect this is at least partly due to the way the 560 Ti directs airflow directly at the CPU by effectively blocking the front of the video card off completely from the rest of the system.
The SG05 again produces moderate temperatures for both the GTX 560 Ti and the GTS 450. In fact, impressively enough the GTX 560 Ti's temperatures are roughly on par with many ATX cases; the ventilation on the side of the SG05 definitely seems to be doing its job.
Unfortunately, SSD temperatures are where things get a bit sticky with the GTX 560 Ti. Because of the way it blocks off the side vent coupled with the heat it generates, airflow around the drive bay winds up being fairly minimal. Heat gets trapped between the video card and the drive bay, just like it does in Cooler Master's enclosure.
The CPU fan also seems to be working a bit harder, though ~2% is essentially within the margin of error. SilverStone's FT03 Mini has a superior airflow design for the CPU, no way around it. It shares the same basic chassis as the Sugo SG05, but enjoys a beefy 140mm Air Penetrator intake fan.
Once again fan speed falls in line, though I'm keen to point out the GTX 560 Ti's fan speed in the SG05 is actually comparable to some of our best ATX form factor case results. That extensive ventilation pays big dividends for SilverStone.
The noise results bear out one of my main theories of case design, too: smart airflow design can do wonders for keeping noise levels low. By being a bit more closed off, Cooler Master's design actually increases the amount of noise generated since the fans have to work harder. The SG05 is by no means quiet, but it's not spectacularly loud either. I'm not sure you could really make a case this small that runs much quieter; at that point you really need to start cherry picking components.

This is exactly what I wanted to say.If you aren't into heavy gaming (I just program) this thing will idle well below 50W and will hardly go over 150W if you load it.
The 300W supply will be much more efficient in this kind of usage. I wish the review had added the power used in idle and under load (with and without an additional graphics card). That would provide the curious with the right information if 300W is enough for them.
For those of us who care about the environment (or like saving on the energy bill) it is quite hard to find a low Wattage good quality power supply. Compliments to Silverstone to providing one. Hopefully there will be a 200W option next year :)

Just to add to this: More efficiency = less heat generated in the PSU for a given load. With these SFX PSUs being limited to 80mm fans, they can't really move much air without ramping the speed up to audible levels. It's even worse because these cases are more likely to be sitting on your desk close to your ears.That said, it really depends on the design of the specific PSUs, and since the power draw is so small anyway, any small differences in efficiency might not be very noticeable in practice. A good 450W will probably not be significantly worse than a budget 300W for example. I certainly wouldn't give up something like front panel USB 3.0 just to get the smaller PSU, for example.

I am with the 300W fans, and would go even more extreme towards an external 200W brick...... and a smaller enclosure. enclosures are like suitcases, each size has its justification!RaistlinZ - Sunday, August 19, 2012 - link
I'm sorry, but your choice of PSU really isn't going to have one iota of difference on the global environment. Seriously.Zap - Monday, August 20, 2012 - link

As always, great review.I also own such a MiniITX case, just with a different front (SG06). I run it with a quad core Intel CPU and EVGA GTX560Ti. Runs fine and silent. Silent but only because I modded the case.
The ODD isn't really worth the wasted space. I haven't used it at all since I own the case (1 year), but because some people still use DVD or BluRay they should keep it, maybe optional?
The 3.5" clamp is somehow stupid, better inlcude a few 2.5" holdings. (That's what I did) Make an open air construction and place it in front of the front intake fan. Then customers can add 3 or 4 2.5" HDDs, like 1 SSD, 3 RAID 1TB drives. Because the HDD holding is a lightweight construction, they don't block the air flow and get cooled fine. (I put 3 HDDs in a closed custom made shock absorbing case (tube) with a low spinning fan which blows air through the tube, thus I don't hear the HDDs at all. But such a construction might be too expensive for mass production)
But the really annoying part is the PSU fan. The fan is too small. In the current design most of the air must get blown through the PSU fan. The heated air from the HDDs, Mainboard and mainly CPU + the heat produced by the PSU must get pushed through the tiny PSU with a 80mm fan. That's idiotic. It's loud and reduces the lifetime of any PSU drastically. I had to replace the 80mm fan with a 120mm fan and made a custom case for the PSU, now it's silent and cool.
The case itself is very clairaudient because of the huge amount of air holes. This makes the noisy PSU even more annyoing and difficult to make the PC silent with standard components.
Because the PSU issue isn't solveable with the current design and default PSU cases, and the case is very clairaudient at all, Silverstone should redesign the whole case and optimize the airflow. Like putting the PSU at the front, reduce the amount of air holes but optimize the air flow, maybe put the mainboard on the side & GPU to the bottom (better airflow for the mainboard, GPU fan noise gets absorbed from the desk), or anything else.
It's difficult to build a small system which is both powerful and silent with standard components. For the money it's a great case, but if you want it silent, you have to mod it, which is the only real drawback I have. Once you've done that, you'll have a powerful PC in the smallest case possible.

Why doesn't the PSU take in fresh air via the top? Would seem like a much better design.Socaddict - Sunday, August 19, 2012 - link
I have the PSU in mine flipped. Didn't take any real work to sort out.hybridE4t - Monday, August 20, 2012 - link
Having it pull air from inside the case then exhausting it will aid throughput of air through the entire case and lead to better cooling throughout, particluarly if your other fans are orientated to complement this push-pull effect. Not recommended for low quality PSUs but as SilverStone are supplying both the case and PSU the fact they've orientated it this way suggests that they're confident it provides a net benefit.Jumpman23 - Sunday, August 19, 2012 - link
I've been reading reviews on Newegg on the older version of this case with the 450W PSU and a lot of people are saying that the connector included in the PSU is wrong for slim optical drives and you need to buy a separate adapter in order for it to work. Is this still the case with this? If it is, it's a pretty big oversight.
