I need a new HTPC since I have FiOS and my 2-year old daughter broke my current pc (how, I have no idea). And since I have FiOS w/ DVR, all I would need this new system to do would be to serve as a front end to play DVDs stored on my home-built NAS and any local DVDs (Blu-Ray option?) people happen to bring over. That means I don't need a big hard drive or a super powerful processor. I would love to build something the size of my Wii that could do all that. Anyone have any experience building something using the mini-ITX form factor?

Are there any websites or resources to look at other than www.mini-itx.com? I'm also considering the possibility of network booting so I wouldn't even need a hard drive in this system. Is there any benefit to that? I couldn't find any online resources for network-based booting (probably wasn't using the correct search words) so if I prefer MCE 2005 because I'm used to it and I like it, but what are people's experiences with MythTV compared to MCE?

Anyone have any suggestions for a good build? I know via puts out little systems for use in really small computers, but I don't know what their processing capabilities are as far as handling Hi-Def DVDs and streaming video. I have heard good early reviews of intel's G45 chipset, so that's an option as well.

Your assistance is appreciated as always

Oh you lucky bastard, you have TV in your area? I used to work for Verizon but in an area where just the internet was available.

I like this board, the AOpen i965MGT-LA

Unfortunately I only have experience with AOpen ITX boards. You only need something small eh?

BluRay decoding requires either a powerful CPU or a powerful dedicated GPU. I can tell you from experience, the D201GLY2 does not have enough power to decode high-def material, nor does it have a PCIe slot for a dedicated graphics card. The processor on the D201GLY2 is far more powerful than anything VIA has to offer, so those boards are simply out of the question.

There are quite a few people interested in mini-ITX systems over a SilentPCReview.com. From what I've read, Intel is due to release a set of new mini-ITX boards that support most of their Core2Duo lineup. See here.

Is there any reason why the HTPC has to be mini-ITX? If you were to go with a mATX setup, you'd save quite a bit of money, and the system would be much easier to cool (in other words - it can be quieter). There are some nice pre-built HTPC barebones systems that can be bought for very reasonable prices. Something like the Hiper Media Center PC HMC-2K53A-A3 might be up your alley. I've played with the setup at SPCR's lab and I have to say - it's very slick.

I wouldn't recommend going diskless. Buy yourself a notebook hard drive for the system drive, and then use a mapped network drive for your actual storage medium. I've got a setup similar to that in my XBMC and I couldnt be happier.

@ Tripredacus:
Yeah, TV moved in about 5 months ago. I couldn't wait to drop Cox Cable.

@ Zxian:
There's no particular reason it has to be mini-itx, I was looking at mini-itx specifically because of the size and my requirements. I hope Intel does a good job w/ the g45 chipset. At this point it looks like my best option if I want to go super SFF. I'll still look at micro-atx as there's certainly more head-room. I didn't know about SilentPCReview, so thanks!

One miconception about mini-ITX systems is that they're always smaller than microATX setups, but it all comes down to the additional hardware and the case you put it all in.

Depending on whether it fits, I'd rather go for a slim, wide case than a narrow, taller case. It usually looks better as part of a home theatre setup.
