The small form factor (SFF) HTPC market has been steadily growing over the last few years. As mobile processors become more and more powerful, it is becoming easier for users to be satisfied with their performance even in desktop configurations.

The DIY HTPC crowd has a marked preference for mini-ITX motherboards and cases. However, the excessive TDP of desktop CPUs results in complicated thermal designs and noisy results. Thermal designs for systems with mobile CPUs with 35W TDPs are fairly straightforward and not very noisy. In fact, it is even possible to create systems which are fully passively cooled.

ASRock has three HTPC families catering to the entry level, mid-range and high-end markets. While the ION based HTPCs form the entry level (and have since been discontinued), the Core series serves the mid-range and the Vision series caters to the high-end. Today, we will be looking in detail at the Vision 3D 252B, the second generation Vision 3D series HTPC from ASRock. First off, let us take a look at the configuration of the review unit sent to us by ASRock

    I agree that the necessary information is spread out over multiple sites / reviews. We will work towards maintaining a database for easy access to all the information from a central point. Reply

    There's already an extensive guide:

    An alternative to MPC-HC is a Korean product called Pot player:

    I've used both players with a GTS 450, an AMD 6950 and an AMD 5670 without issue after following the guides.

    First off, I skimmed the article, so forgive me if this is really obvious. Second, I have an admitted Mac bias, so that's where this is coming from. So here goes:

    With the exception of the Blu-Ray drive and USB3, is there really much that makes this worth so much more than a Mac Mini? I'm thinking the $799, i7, Radeon 6670m equipped model.

    $100 to load Windows onto it (if that's your flavor), and $200 should get you a blu-ray player - that leaves that set up $100 cheaper than the ASRock...

    The Mac mini does dual display, has HDMI out, and has an optical audio output as well. Admittedly, the SD Card reader on the back is less easy to get to than a reader on the front, and the base HDD is smaller (500 GB).

    Different strokes for different folks?

    But Mac mini does not bitstream HD audio to AV as far as i know. And this is the most critical point in my opinion for HTPC. Reply

    1.2k for 1.2 k I can have a 2500k cpu a crucial 256gb ssd a 2tb hdd a blu ray from asus 8gb ram a mobo from asus the catch is I need a 14 by 14 by 7 inch case.

    Any real hi end ht has amps, larger speakers ,large tv. Some subs not one sub.

    A gear rack and hiding a case the size of 14 by 14 by 7 on a gear rack is easy.

    This is for a design freak with tiny little bose speakers and a wall mount led flat screen.

    while that ht is costly ie hi end it makes poor quality sound.

    This is a HTPC for the high end home theater. Nothing prevents you from routing the HDMI output from the Vision 3D 252B to an amp / pre-amps and use that to drive the large speakers. Reply

    Or potentially it's for people who are limited on storage rack space. My five level rack currently houses my blu-ray player, receiver, and dedicated stereo amp, as well as my cable modem and router which live on one shelf.

    If I were to replace my receiver (currently acting as my pre/pro) with a dedicated pre/pro and another amp to do surround duties, I wouldn't have another entire shelf for a big box htpc - I'd only have the space next to the modem and router to share.

    Maybe I'm just not seeing this in the review, but what software did you use to record the graphs of power usage? Reply
  • ganeshts - Monday, May 07, 2012 - link

    The graphs are from HWInfo. The software is capable of much more than just simple graphing. Here is another screenshot (and the link to the software):

    I used to build HTPCs back in the day to record shows as a glorified DVR. There's no bundled tuner. What's the point of HTPCs nowadays, assuming you're not using them as a DVR?

    I can do pretty much all of these things this machine can do with a Blu-Ray player, Google TV, integrated TV software, a Roku box, or just an HDMI out to an existing tablet or laptop PC. And the prices for these approaches ranges from free to $200 depending on what equipment you already have?

    Even for massive movie hoarders who want to stream their collection, you can do that with most of these devices.
