The fastest sub-5L system possible :p

Hi there, I've just finished building my first super HTPC (as I like to call 'em) and a need took me to post my results (my system) here.
First off I have to say that my camera died a few days ago so you'd have to bear with stock photos (of the items) for the time being...

Anyhow before describing the system let me say that my crafting abilities are close to nil, but I do have an eye for choosing good hardware for my/one's need. This means that I had to work with stock items, and not the slightest customization of any physical objects went in.

My goal was to build the fastest possible system which is less than 5 Liters in volume (smaller than modern consoles). So here it is:
(note: since I'm European all prices are in Euro)

The case I used is called "E-2010" itx case. I bought it from an Austrian guy who had it supplied from a Chinese vendor, it's not easy to be found and indeed it may be the only case that measures less than 5L (it's 280x240x70, all in mm) yet it can house a full height pci express card.
Here's how it looks:

As you can see its build quality is a bit flimsy, but the way in which I have it placed only the front can be seen, so it actually looks quite decent.
Price: 40€


The motherboard of my choice was Zotac Z68-ITX. It comes with an mSata connector (which will come handy later).
Price: 140€

For CPU I preferred the i7-2500K since the difference from the 2600k is minor in performance yet steep in pricing.
Price: 160€

Memory: I bought the cheapest I can find because -again- the differences in Ram Perfomance these days are minimal at best. So 8GB of 1333MHz DDR3 it is.
Price: 35€

And now the interesting part begins

In such a small case one can easily think that any high caliber GPU would not fit either due to thermal or plain physical issues. Yet the Powercolor HD6850 single slot I bought not only fit, but it actually did so quite comfortably (exactly undeneath the case's grill holes).
It cost: 160€


So that to fit it facing upwards (the case could only take cards that face downwards, suicidal for such power hungry modules) I had to buy a 6'' right-turned PCI-E Extender
Price: 50€

but also an inverted PCI-Express bracket, so that my card could mount perfectly on the back of my case.
Price: 10€


Of course I also had to remove (unscrew) the Optical/HDD cage that came with the case so that to fit the card (the case has 280MM depth, the card was/is 240mm). Which would create an issue since there was no room for HDD left anymore. But this time around my choice of Mainboard came to the rescue. You see it supports mSata disks (AFAIK the first with this feature).

So I mounted to it an 80GB Intel 310 SSD, which in Real time performance is about as fast as any modern SSD
Price: 140€


(I could go for an 120GB Sandforce SSD, but the cost would be over twice than what I paid, so I figured it wouldn't worth the cost for the time being - I guess I'll simply upgrade in the close future, when prices go down)

Lastly (to top it of) one can rightfully wonder how come so much hardware can be supplied with power efficiently, especially since a normal PSU cannot fit in such a small case. My solution came in the form of PW-200-M pico-PSU which is the only PSU of such small footprint which can handle 13.5A of +12v
Price: 40€

Of course I aslo had to buy an AC-DC adapter capable of suppling my pico-PSU with enough Amps and the only I found was/is this one (16A, 12V, 192w)
Price: 60€


As you may be able to see the above PC cost me in the total 835€ (add a 10% over that amount to be adjusted to USD prices). That's thrice the amount one would pay for a console these days (which are someting of an equal size), but now consider the gains:

It's far faster than anything that small.
It boots in 20 seconds (cold boot; milliseconds if it's in sleep mode).
It plays everything comfortably at 1080p
I adjusted it (through bios and afterburner) to be *completely* silent when it's idle or playing a movie. While when it games it's barely audible (and the sound is being covered by the games' sounds), certainly less loud than X360. My temps never exceed the acceptable limits.
Through the power of Media-Portal, it's my family's (wifey's and kids') media center for everyting, from Live TV, to Movies, Youtube, even Gaming and basic surfing. Plus I've skinned MP so everything looks very slick.
It uses the excess of it's computing power (4 cores if you can remember) to seed Live TV streams to the network (for anyone who has an adroid phone and/or a laptop/PC).
I've tried the two most popular emulators (for PS2 and Wii) and it can play them at full frames. So I can literally buy games for Nintendo Wii (for the kids) and having them play on my TV (w/t actually having a Nintendo wii) @ 1080p!!
There's nothing that I threw at it that it cannot chew through its bones. Oh forgot to add, I even managed to overclock my GPU (@ 870/1150) all the while having it under-volted (15% less voltage), same with the CPU (the UV part I mean).

As you may see, it's the ultimate machine that small. I post it here mainly so that I can see if there are others that ever had experimented with ultra small HTPCs. In fact I would be glad to see if someone else did sth similar (and what *exactly* did he do).

...that is all for the time being (sorry for extremely the long post :D )
 
Cool build, waiting for the pictures!

But, €50 for a PCI-ex raiser?!?! $ 4.85 on Ebay

The pictures would have to wait a bit, until I'd get my camera back and working. I hope in a few day I would edit my post to include them... To give you a sense of scale though, that's almost *exactly* how "big" my system is (the black box on the left)
(sorry to say but I doubt that there are many who have smaller systems in here, most itx systems are about thrice this size).

I paid so much for the riser because it is the only which could work for my case. I own some of the cheap risers which you can find on eBay but while they're great for small cards, they sort of suck for graphic cards. They do not have noise shielding, which lead them more often than not, not to let the card to boot and when she does, she's runnig about/around 30% slower. Unacceptable for a system that I wanted (it) to be as fast as possible. Also they're pretty short to top it of (I found none which is bigger than 5'')


...the cooler I used was an old Zalman that I had to cool my GFX (it's a dual purpose cooler), that I managed to fit to the 1155 holes, all the while it came just about right heightwise. I may consider to buy a better one in the future, but she seems to do her work very well anyhow.


Oh BTW I considered at first to buy the Z68-itx Supreme by Zotac, so that to use it's embedded GT430 card for physx (via the physx hack) but its punny pci express port (x4) detered her from me. Pity it would create

...still no pics, I hope that I would up them soon. :)

...sadly -as I see- there's no much interest in ultra small HTPCs -like the one above. Most people are into much bigger machines for their living room I see. But -for some reason I think- it's a greater achievement to fit so much power in such a small space than the opposite..
 
Had a few super dense mitx builds when I had via mitx stuff. Since I learned how mitx shoebox could be a decent mitx powerhouse, I haven't really looked back. That and I still have too many laptps.


Don't worry I do have this thread favorited. I just have litte to contribute to your work :( I'm sure there are others like me who are merely patiently watching :)
