HTPC enthusiasts are often concerned about the quality of pictures output by the system. While this is a very subjective metric, we have decided to take as much of an objective approach as possible. Starting with the Core 100 review, we have been using the HQV 2.0 benchmark for this purpose.

The HQV 2.0 test suite consists of 39 different streams divided into 4 different classes. The playback device is assigned scores for each, depending on how well it plays the stream. Each test was repeated multiple times to ensure that the correct score was assigned. The scoring details are available in the testing guide on the HQV website. In the table below, we indicate the maximum score possible for each test, and how much the Zino 410 was able to get.

To put this score in context, let us look at the HQV 2.0 scores obtained in some of our earlier tests.

HQV 2.0 Benchmark Scores

Amongst SFF HTPCs, the Zino 410 undoubtedly has the best HQV score. However, it is unable to approach the high scores obtained by the desktop 5570. Note that the Zino 410 is able to achieve this because none of the other GPUs have proper cadence detection (which forms a bulk of the score).

Unless the end usage scenario involves heavy viewing of streams needing cadence detection, it is hard to recommend the Zino 410's Mobility 5450 on the basis of the HQV scores.

    Wouldn't the motherboard have to be grounded to the case? I don't think many manufactuers has designed the motherboard to be hanging in the middle of the case. If you flipped the motherboard upside down; it would be practically the same thing, but less efficient. Now, you can put the motherboard on the side of the case, but then it would be a normal size desktop PC and wouldn't be a HTPC anymore. I'm just visualizing this in my head. I could be wrong. Futhermore, they would need to redesign the heatsink with less space they have to work with. We're talking about a compact HTPC here and not one of those no cover, Antec custom cases.

    Also, I don't see the point of having a hard drive underneath the motherboard because the motherboard would practically cut the HTPC in half; trapping all the heat coming from the hard drive on the bottom half of the HTPC. They could reengineere the entire thermal design, but this would mean starting from scratch again. Like adding a bottom fan to pull out hot air and making holes on the sides of the cases, etc. There are just too many variables to this.

    Just my opinion. Don't take it too seriously.

    The reason I ask is that I have a Morena case that works as I have described.

    Now the Morena case has a number of flaws (cheap plastic being the least of the problems) which with a bit of "apple" design could be seriously improved but it runs 24/7 as my atom server without any problems and you can feel the convection working.

    Neither HD or optical drive get that hot - at least not compared to the CPU!

    It is not as though you need to cut the case in half because the height of a slim line optical and a 2.5" HD is something like 15mm max - it also allows for better cable management.

    It is just I have this nagging feeling that the designs are based on "this is how we have always done it" rather than looking at it logically - or maybe because the designers expected all cases to be placed vertically rather than horizontally

    Maybe it is also because I am looking to build an HTPC and keep wanting to put a slow running fan in the top to keep memory and CPU cool - with a case that is barely 100 mm tall

    Technically you could build something mostly like this with off the shelf components, though it might well be more expensive.

    The mobile processors are not cheap at all, and trying to find them on sale at Newegg or one of the top e-tailers is a tall task..

    $775 for this? I don't see what HTPCs are more expensive than laptops and desktops.

    Hi Ganesh,
    1) Thanks for your excellent review on this Dino and ASRock Vision.
    2) The points that i missed from your review are:
    a) Using BluRay disc, are they able to stream Dolby TrueHD or DTS HD Master codec from HTPC (Dell/ASRock) to your Onkyo TX-SR606 via HDMI? You should be able to see the codec being display on your Onkyo set.
    b) Are they able to stream blu ray and dvd iso files from NAS or HDD?

    Regards
    Len

    Sorry for the late reply, but the answers to your questions are:

    1. Yes, but don't expect the bundled PDVD to play nice with your requirements. You are better off investing in a full featured BR software player than what Dell bundles. Otherwise, make a backup of your BR with MakeMKV and play with open source players. Bitstreaming works fully well.

    2. Yes, it can easily stream from NAS or external HDDs provided you have the appropriate software players. [ PowerDVD / TMT / WinDVD ]

    I purchased this unit in January 2011,received in February. For two months I was fighting on my own with:
    1.Dropping WiFi signal 5 feet away from 802.11 N router;
    2.Extremely poor HDMI video.

    Then I decided take it to Dell tech support. After many hours wasted on phone they decided to replace motherboard, sent tech to my house, who replaced motherboard and sent back my motherboard with external video card. Neither the person who sent m/b for replacement, nor tech himself did not know, that there is external video card, which went away. No surprises, there was no video after this 'repair". They sent another tech with another m/b, replaced it... no video. Only the third tech with the third m/b asked me, where is you video card??? Afetr long fighting they sent me refurbished system, which is working, but the HDMI output is as awful, as it was, so I connected it via VGA output and sound cable and it works.
    By the way, wireless card replacement fixed connectivity problem.
    So my moral: Dell's service in India and techs in the USA usually don't know anything, HDMI output in this system is really bad.

    I used this as a home theater PC and it works great. It records four shows simultaneously via a couple of HDHomeRun external dual tuners. I can even watch a TV show as this is happening with no issues. And thanks to gigabit networking I can listen to music streamed from a media server. It includes PowerDVD integrated with Windows Media Center to play Blu-rays and [upscaled] DVDs.

    Changing the optical drive from a nonmotorized tray model to a slot-load model. The current tray only extends part way and requires a bit more effort to load/unload than a user would expect. One can easily move the HTPC while doing this and even damage the tray.
