I haven’t built a HTPC before and haven’t built any kind of PC for nearly 3 years, but many and often before that. Im going to try and document (at least some of) this build, which I hope might be of use to others doing or thinking about doing a HTPC build.

I have been specing this build for about 6 months, I bought a few bits and pieces during that time, but didn’t take the final step and order the majority of the parts until last week.

Why so long specing? Long story, but the two major delays were deciding on a case and deciding on a motherboard. Its taken me over 4 months or hard looking to find a board I was happy with :)

Aim of this project
Create a quiet and low power PC that I can use to watch/record freeview TV, watch DVD and Blu-Ray. (Cant get cable or satelite TV where I live atm)

I wasn’t too bothered about how small the case was, but I did want it to look like Hi-Fi equipment not a PC. I didn’t have a fixed budget and was happy to buy everything new rather than reusing old stuff lying around. Originally I wanted to also play games on this, but along the road I realised it was going to go against my quiet and low power requirement, so there is no need to point out to me this wont run Crisis very well :)
I can still fit a dedicated GFX card in there if everything goes ****-up :)

Some of my choices probably seem a bit “wrong”. I know I don’t need a 450W PSU for example, but there was always some reason for my choices (I hope so anyway).


Parts List (bought and currently building):
Processor: AMD Athlon X2 5050e Socket AM2 45W
Motherboard: Asus M4A78-EM (mATX)
Memory: OCZ 4GB Kit (2x2GB) 800MHz/PC2-6400 Platinum
Graphics Card(s): ATI radeon HD 3200 (integrated to motherboard)
TV Card: Hauppauge NOVA-T-500
Hard Drive(s): 500GB Samsung HD502HI EcoGreen
Optical Drive(s): LG GGC-H20L Black
Cooling: Zalman CNPS8700-NT & 2 x 120mm Sharkoon Silent Eagle
Sound Card: ALC887 (integrated to motherboard)
Case: Antec Fusion Remote Silver (v2) (only takes mATX)
Power Supply: 450W Be Quiet Dark Power PRO
Keyboard/Mouse: Gyration GC215 GO 2.4GHz Optical Air Suite

Why I chose these parts:
Processor: Low power, low heat (slightly slower than intel, don’t care much)
Motherboard: Needed integrated GFX that would run blu-ray and reasonable integrated sound chip.
Memory: One of the fastest 800 chips on the boards compatible list. Im too chicken to experiment :) Ive had good experience with OCZ in the past.
Graphics Card(s): Should run Blu-Ray and older games OK. Ive tried to setup cooling specifically to tackle the overheating these chipset boards often suffer from.
TV Card: heard good things about this and someone in a forum said this worked OK with Linux :) I know the bundled software is useless, I don’t plan to use it.
Hard Drive(s): Quiet and low power hdd that give reasonable performance – seemed ideal choice. I dont need big capacity I want to use external storage for media (maybe eSata drives – haven’t decided yet).
Optical Drive(s): Rushed this choice at the end, someone said it was not that noisy – hoping it works out OK
Cooling: I did consider passive cooling for the CPU, but decided to go for extra airflow over the MB instead. Sharkoon push more air and quieter than the stock case fans.
Sound Card: I think dedicated sound card would be a bit of overkill
Case: This like all HTPC cases has its problems, but I think it has less than the rest. Im fine with it being quiet large. I actually wanted black, but got the silver cheap on a special offer :)
Power Supply: This is meant to be deathly quiet and reliable. 450W is overkill, but they don’t make a lower watt one :rolleyes:
Keyboard/Mouse: Saw this demonstrated on Youtube. I like the idea of using a mouse from my sofa. The Logitech alternative seemed gimmicky and more expensive for little benefit.

Cost

Total cost of parts so far: £659.10 (inc vat)
Does not include operating system or screen

Still to order or undecided:

Screen:
I still need to buy a new TV, but I’m only going to order this once I get the system up and working OK :)
Maybe the Sony Bravia KDL32V5500U

Operating System:
I haven’t totally decided on this yet, but I’m planning to do WinXP32 / Mythbuntu64 dual boot. Myth will be the main OS, XP is just so I have the option of playing (older) games if I really want to. My first time using linux so expecting that to be an adventure.

My Parts have arrived :cool:

So many cables! This case does not seem big anymore :(

IT ALL FITS! Just... :D

Current Build Progress
I’ve now done most of the physical building. Getting all the cables to fit in has been a pain. Things are so close together in this case I have loads of extra cabling floating around that I don’t need. Worst problem so far has been the lack of space between the PSU and optical drive. The drop in design on the 5.25 caddy means I cant plug in the PSU cables until I drop in the caddy, but when I do that I have hardly any room to work between the two. I considered asking my girlfriend to plug in the PSU cables because of her smaller fingers, but thought better of it and mashed mine instead until I finally got it done :D

Next I will be tackling the BIOS and OSs (plural). I might take a bit of a rest first though as my fingers are hurting atm :)
 
Your PSU looks huge. I have the Antec NSK 2480 (same layout inside I think?) and am using the supplied 380w PSU:

HTPC%201%20640x480.jpg


I also ran the CPU power cable under the motherboard as it laid quite flat.
 
What cpu and cooler have you used fobose and what temps are you getting?

I'm going to build a HTPC soon and i need it to be as silent as my modded Topfield.

Additional: I'ld be interested to know how quiet your final build is too, Xerai, as your using the PSU i'll be using.
 
I used a E5200 and a scythe mini ninja. One of my temp sensors are stuck on my CPU (at 55c), but the other core idles at 36-37c, and load temp after 30mins of everest stability test it gets to 44-45c. I think the mobo temp is always around the 34c mark.

I also have the Asus Qfan controller one of the noctua 1200rpm fans which runs around 800rpm, and I have a resistor cable on the other fan which I think makes it 500rpm.

is it me or is the RAM not placed so it is running in DUAL channel mode? or is it different for this MB?

Looks like his CPU cooler is blocking the first two slots..
 
Mind if we see the front of the case? I like cases!

Front View (sorry camera distorted perspective a bit)

Fobose: I didnt think about running the power cable under the MB, but as its sleeved I dont think it would have fit. My case didnt come with PSU, and I had no idea how huge this PSU was going to be until I actually tried to fit it :)

There is nearly 1cm gap between the top of the DIMMs and the bottom of the CPU fan which does hang over the banks slightly. Extra cooling :cool:

Got me thinking, doesnt actualy specifically say in the MB manual, but I think its correct :)
 
I'm getting the black version of your case,Xerai - so this is a great run thorugh for me and your pic of the case has made me certain it's the right choice aesthetically, thanks (Nad, like in design - simple yet sleek).

I'll be using an E5200 and if the scythe mini ninja can cool it passively then that's the route i'll be following - but like, Xerai, i'll be using a BeQuiet psu.

Fobose - is your rig very quiet? (As i plan to use modded noctua fans too.)

Xerai, would be very intrested in your noise levels too as youtr using the Zalman?
 
It is very quiet, as I dont use a CPU fan on the ninja and the noctua's are running at half speed or lower. I can just about hear the PSU if I put my head in the cabinet its in though.

My build was a budget build which is why I opted for the NSK 2480 with the supplied PSU. I also had the noctua's laying around doing nothing so decided to use them rather than the supplied fans.
 
Thanks for the reply, fobose - mine will be sitting on an open shelf so hopefully with the BeQuiet PSU it'll be just as silent as yours in its cabinet. My aim is to only just hear the hard drive power up when it's recording.

It's got to be as quiet as my modded Topfield - otherwise i'll have get rid of it and buy the latest Topfield.

Looking good Xerai, how's it running?
 
Noise, Heat and Power usage


Noise Levels
Be Quiet PSU: Cant even hear it at all even if I put my ear right up to it. In a quiet room with the case lid off there is still no sound at all…
NB: The PSU fan is actually spinning not broken or off btw :)

The case fans connected to the PSU are not spinning at all. Not sure when these turn on, maybe when the PSU is under heavy load, in which case they may never turn on in this system :)

Zalman CNPS8700-NT: This is noisy even though I’ve turned it down to 4v already. Might be I’m just noticing it more because there is zero sound coming from anything else in the system. I’ll have to see what it sounds like when its all closed up and under my TV.

NB: When I have my main PC on in the same room I cant hear the Zalman anymore.


Power Useage

memtestw_s.jpg

System off, but connected to mains: Draws 2W
In Bios: Draws 64W
Running Memtest: Draws about 77W
Peek: Havent seen it go over mid 80s W yet.


Heat

Temperature shown (32C) is after about 2 hours on and just finished Memtest

Build Progress
Still haven’t installed anything, been running Mythbuntu from CD to try things out. Havent fitted the TV card yet.

Thanks for the detailed noise info Xerai, that's helped me a lot. I think i'm going to go down the passive route like fobose.

It's been a great thread for me as all of you are using the case i want to get -so cheers - always very helpful to get an incite into how easy/difficult things are to fit. It's roomier than i expected which is reassuring.

How is that? I thought if they were connected directly to the PSU they would just spin by default. How do they work?

The PSU has modular connections and has special (fan only) connections which my case fans are connected to. Im not sure if the fans are meant to be on all the time or not. Ill investigate this later as have to look at a few other things first.

Back plate is blocking the LAN port, only just noticed this - got to take the board out again :rolleyes:

Build Progress
HDD partitioned in to 5 parts: 1 for WinXP32, 3 for Mythbuntu, 1 for Data
WinXP32 now installed, draws about 50W when idle on desktop.

Cheers - i'll be interested to know your findings.

Very annoying for you - hope it's not too much effort to get it sorted. I hate having to dis-assemble a rig you've just built for minor problems.
 
Wasn’t too hard to unblock the LAN port after all, just had to take the screws out of the board and lift it slightly, only took 2mins.

Been thinking about the others on here that are using passive CPU cooling. Are you guys using your case fans to blow in or out of the case?

Reason I ask is:

In the Antec Fusion case manual it says the case fans are to blow air out of the case. I think this is so it pulls in air from under the case and past the HDD for example.

If case fans are blowing air out there is not going to be much flow over the CPU or north part of the motherboard. Don’t you get heat problems with the CPU and integrated GPU?

If you set the case fans to blow in, you will have cooling for the CPU, but I think it screws up the airflow design Antec want to happen?

I think my case airflow works like this
