HTPC enthusiasts are rightly concerned about the noise factor, heat and power consumption, ease of usage and many other criteria. We will tackle each of these concerns one by one in this section.
Noise
ASRock claims that the Core 100 HT-BD produces less than 25dB of noise. Under lab testing conditions, such performance is indeed possible. We decided to get hold of one of the sound meters used in setting up home theater speakers to verify whether the claims were true. Being a hobbyist sound meter, it wasn't very sensitive. The measurable sound range was only 50 - 130 dB, and there was a concern that the Core 100 would be too silent for the sound meter to pick up. As it turned out, while running Prime95 at full throttle (100% CPU utilization), the fans kicked in at full speed. The sound meter registered between 53 and 55 dB very close to the unit. [ See UPDATE below for a more practical measurement ]
The fan noise is quite audible if one sits very close to the unit. From 8 ft away, even with the unit in the open, we could barely hear it. Noise, however, is a very subjective issue. We hope the quoted number will help give readers an idea of how noisy the system gets when fully loaded. If the unit is going to be installed inside a cabinet of some sort, the noise factor becomes a non-issue.
UPDATE: One of the reasons we kept our sound detector very close to the unit was because it refused to register any measurement at the usual practical distances. While waiting to get hold of a more sensitive sound meter, we asked ASRock for lab results of sound measurement at full throttle. They were happy to oblige us with the following photographs and video from their anechoic chamber. It appears that the sound level is less than 35dB at a distance of 2 ft. even with all fans in action.
Power Consumption
In order to get an idea of the power consumption numbers, the Prime95 benchmark was let run overnight to keep the system completely loaded for an extended duration. All the four 'cores' of the CPU were pegged at 100% throughout, and we found an average power consumption of less than 48 W. At idle, the system consumed around 18 W.
These type of power consumption numbers have been enabled by ASRock's choice of going in for an Arrandale instead of a Clarkdale platform. This has resulted in a smaller form factor case design for the mini-ITX motherboard. Since there is not much heat to be dissipated, the cooling system is also appropriately small and silent.
Ease of Use
HTPC enthusiasts are concerned about how easy it is for their system to come out of standby. Existence of HDMI handshake issues upon return from standby is also a deal breaker for many. Fortunately, the Core 100 HT-BD has no issues in these two aspects. As long as the AC power adapter is connected to the system, the bundled MCE remote can be used to boot the system (even if the PC had been shut down previously). In order to shorten the boot times, ASRock supplies an Instant Boot utility. Using this, whenver the Core 100 HT-BD is shut down, it boots up once again and shuts down before the power can be safely removed. Upon power up, the boot up is instantaneous. If the user wants to put the PC in sleep mode, ASRock also supplies a Goodnight LED feature in the BIOS, which turns off the bright blue blinking LED in front. The MCE remote can also be used to bring the PC out of sleep mode.
Within Windows, the MCE remote can be made to work with a variety of applications such as XBMC, MediaPortal, MPC-HC and of course, Windows 7 Media Center. Blu Ray players such as PowerDVD and ArcSoft TMT can also be controlled with the help of the MCE remote. For the ideal I/O scenario, one probably needs to purchase a wireless keyboard / mouse combo.
It was seen in an earlier section that the Core 100 HT-BD happened to score quite well in the Anandtech Media Streamer Test Suite. The unit could playback all files using one program or the other, and people expect nothing else from a HTPC. Unfortunately, there is no single unified interface (from XBMC or MediaPortal or any other similar program) which could successfully play back all the files from within. There is definitely an ease of use issue existing here. However, this is not ASRock's fault, and will probably continue to exist on all Clarkdale / Arrandale platforms. Hopefully, projects such as XBMC's DSPlayer mature rapidly to alleviate this problem.

This system is capable of dobly truHD and DTS HD. A ION system is not capable of decoding of those sounds format...So this system will appeal heavily to someone that wants a small nettop type system with a BD and good encoding performance. With any nettop you are going to have to use NAS storage anyways, but this system will allow more internal expansion than most others.. But if you wanted to, you could pair it with an external drive cage.. I wouldn't want that in my living room / theater room though.
biggest problem with this system is price.. You can build a great system for a couple hundred less if you are willing to take hours of researching the components and integration. A successful HTPC build will take considerable more time in planning/research than a typical PC/Gaming PC Build....
If you are wanting a powerful, small, efficient, prebuilt nettop, this is the best out there right now!
That is really the only thing i wish Ganesh would of pointed out a little more clearly. The capabilities of the "iGPU" vs an ION.. with the growth of this field, I would love to see a followup review that would pit a custom built (but comparable build) HTPC.. like a Core i3 530 (or maybe an e7200) / H55 with and without an ATI/NVIDIA (non ION) card. This would really give some people something to look at as far as capabilities..
and really, who cares what the remote looks like.. get a Logitech harmony or some other home automation remote... most people will only care about if the IR or RF functionality is already there...

spddemon,Stay tuned for more HTPC reviews in this space. Their performance will be pitted against this solution.
However, ION is passe right now. We will be testing with the ATI 5xxx series and upcoming Nvidia cards.

Upcoming nVidia cards...Hmm I wonder what it is... A low-cost version of fermi or another rebranding of GT2XX cards?

We already published reviews of the GTX460 from the gaming perspective.The card is good from a gaming HTPC perspective because it also supports HD audio bitstreaming.
There are some rumours that Nvidia has lower priced cards coming out in the next 2 months, so we will cover them when they get released :) At the least, we will cover the GTX460.

Thanks for the updates Ganeshts!It looks like your time frame will be perfect for my new HTPC project.
I really hope Nvidia can get some low powered cards out to offer a true HTPC card that covers all the current HD formats/codecs.

Ion can only bitstream LPCM, but I assume the atom cpu is powerful enough to decode truehd in libavcodec.So that only leaves DTS-HD MA as a problem.

Goty,The user can always opt for a USB TV tuner.
If we had an expansion slot for a TV tuner inside this box, the unit wouldn't be based off the HM55 chipset, and wouldn't fit in the sub-50 W power envelop which is a coveted mark in this space.
Further, including a TV tuner in the box would drive up the cost of the system in some areas, as it would be taxed as an entertainment device, rather than a computer.

No one that is serious about using this as a HTPC is going to string USB TV tuners off this thing. You want 2 USB tuners hanging off the back of the machine? How about 4?My HTPC has 7 tuners total. 2xHauppage 2250's, 2xCats Eye 150's and a ATi DCT. Tell me exactly where I'm going to be able to put those on a machine like this.
There needs to be some kind of market differentiation between a HTPC and a Living Room PC. One is for serious use as a DVR and the other is to hook up to the TV and watch some videos/play games/surf the web/Facebook/chat, etc. They are two different markets.

bearxor,You have got an impressive set up.
However, I believe your type of setup is more the exception rather than the norm. The sort of arrangement which will remain a niche for a long time to come. With the advent of IP streaming and availability of TV shows and live sports broadcasts online, I am not even sure people will require so many tuners.
I also think that your sort of setup isn't amenable to the silent, power efficient HTPC that people want (particularly from the viewpoint of media streamers and boxes such as the upcoming Google TV). The latter 'living room PC' that you mention has more potential to explode as a market for manufacturers to exploit, rather than the DVR-centric PC that you envisage.

Exactly, 7 tuners is hardly the norm. I make do without a single one on my HTPC, i have the likes of iplayer if i really feel inclined to drop into the fantastic realm that is daytime television :S
