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.

Aikouka,Thanks for your insights.
1. Customers should hopefully be able to salvage some stuff from their previous setups (Blu-Ray playback software, keyboards and mice etc.)
2. We didn't do exhaustive testing on the VIA codec. Most of the time, it was disabled since we were using audio over HDMI.
3. The sticker is optional ( It comes as a separate label with the package, but you can choose whether to stick it in the front or not :) )
4. The build quality of the remote is not that great and there are better options out there as you observe.
5. Major drawback of ION is the lower general performance, higher power consumption and absence of HD audio bitstreaming. I think the $200 extra is worth it.

1) It'd definitely be nice to harvest a few extra items from previous builds, but maybe a blurb about the overall cost of the software might be nice. I'm not sure, but it might help people sway toward or against the unit as being their Blu-Ray player, since you can easily just buy a decent separate unit for $100 or so. Another aspect that might sway some users is that the BR software will only truly integrate into WMC (last I checked). TMT3 has a plug-in for MediaPortal, but it isn't true integration (just loads the player and minimizes MP).I guess that all kind of goes with your talk on how it can be a pain to get all of the formats working, which let me tell you... I definitely agree with you on that! I had a point where using my laptop as a HTPC, I could get sound while playing MKVs through WMP, but not with WMC. It was the strangest thing :P.
3) Alright, that's good that the sticker is optional ;). I just wish manufacturers would push to not showing the rest of those connectors. It seems the consumer's desire is to have components that are PCs that don't look like PCs, but not many devices have those connections and if they do, they're typically hidden (except the PS3, but they're out of the way).
5) I think the main point I was trying to drive is that even though the ION is inherently weaker, does it still perform the tasks properly? I mean, you can take the kids to school in a Porsche 911 Turbo, but is it a tad bit overkill compared to a Prius? Do you really think the bitstreaming matters that much? I don't think most people would even be able to tell the difference between a good encode output from a SPU and the bitstream... I know I can't! :)
------------------
I like the articles though... I think the HTPCs are going to become more and more popular as people look for non-standard ways to get content. I've actually gone back to using my server as a quasi-HTPC to help alleviate the stress I was putting on my M1530. It's a little better now that I replaced some of its noisy components :).

" 5. Major drawback of ION is the lower general performance, higher power consumption and absence of HD audio bitstreaming. I think the $200 extra is worth it. "And what about picture quality? HQV v 2.0
The ION does the 23,976 but the Core 100HT - does not.
ganeshts - Thursday, July 22, 2010 - link
Good point, vlad08. The point mentioned was the drawbacks of the ION. Of course, if one wants to give the advantages of ION, they are as you mention.I think the average users just set the display refresh rate to 60 Hz and forget about it.. so the 24fps bug doesn't affect those.
Picture quality.. yes, maybe ION is better. We haven't done benchmarking on that platform yet (and will probably not do because it is a product from last year, and we have more exciting Nvidia stuff coming up) to confirm.

Good point about the software costs. This is really a $900+ machine.The Mac Mini competes well with this machine when you consider:
- It comes loaded with some very nice software
- It's light years ahead, aesthetically
- It beats the AsRock on noise and power consumption
- Most people already have a Blu-ray player and don't want the aggravation of dealing with Blu-ray playback on an HTPC. I rarely use my HTPC (Corel WinDVD) to play Blu-rays because of the hassle factor.

While this seems like a good train of thought, it isn't. The poster above points out he uses pro (which is fine, I do too) but there is no reason why Home Premium, which has media center, wouldn't be used by the majority of users. So, $645 + $91. That's it, for anyone wanting the DVD model. Or, about $736.Your comparison at $900 is based on a comparison with a model featuring a Bluray Drive and Bluray software. This is not valid, because you're now comparing apples to oranges ;) The mac mini doesn't have, won't have, and doesn't support a bluray drive. So, the two aren't the same, at all. There just isn't a comparison.
Whether or not people have a seperate player already, there are lots of people who like the idea of 1 single box doing everything, like DVR, DVD, BD, Media Management, etc.
So, let's say you do a comparison on that front. So, the Mac Mini is $699. DVD only. Yes, it comes with software, but not really a front end for this.. so you download Front Row, which was last updated almost 2 years ago. You then go about hacking it to get your supports you need.
And you add a remote control, because the Mac Mini doesn't come with one. So, even if this remote is "flimsly and crap" you add a remote control that is say $50 (and don't say "iPhone" because then you're adding $300 in expense for a remote for everyone who doesn't have one).
So now the cost of your Mini with a remote is basically the same as this with a copy of Win7HP. Except, oh yeah, even if you get the DVD one of this, your ability to later convert to BD is there. Not at all on the other front. Remote wakeup? Yep. Since neither have tuner slots, both would be using say a network tuner. So, Silicon Dust HDHomeRun for both. So a wash on the cost here, except Front Row can't natively manage those tuners for anything, meanwhile Media center can.
You can buy software to do that on the mac.. now you've spent more money.
The Mac Mini is a good unit as a desktop. But for an HTPC, you spend a lot of money for almost no bang. You can get an ION based unit at about $350 that is DVD based that gives you the exact same features.... plus LPCM for your MKVs that the Mini doesn't do worth a damn.
Nothing against the Mac, but not every purpose works out for it. This just isn't one where you say "wow is that a great solution for a Mac". And AppleTV is a laughable product that should die a slow death.

One reason that ASU *cough* I mean ASRock is always the first to put these out is probably that all of their SFF machines use the exact same case, nearly the same packaging, and mostly the same pack-in material.They've used this exact same case all the way back to their first Atom machines. Their ION machines also used this case, as did their bluray machines.
Now that they've introduced some CULV machines, surprise, same case again.

True.And why is it narrow and tall? Why can't they put this in a DVD-sized case with the industry standard width? The front should look just as clean as a nice DVD player, with the front ports, buttons and maybe even the drive behind a fold-down door.

I wish I seen this coming last month Just about finished building one ECS itx mobo and i core 3 530 in jetway 101 case and mines going to end up at about grand after software and tuners. And as far as tuners go for the asrock get a USB or homerun Ethernet.
