Build Recommendation Please: Equivalent/better than Zotac w/ i3

I've been perusing the forums for a week now and I can't seem to get a gripe on what (recent) components I can use to build a new dedicated HTPC. I'm considering buying a prebuilt system, the Zotac ID82 with these specs:

Model ZBOX-ID82-U ZOTAC
Intel Core i3 2330M 2.2 GHz Dual-Core
Intel HM65 Express
Intel HD Graphics 3000
High-definition analog stereo
Optical Digital S/PDIF output
10/100/1000Mbps, WiFi 802.11n/g/b

With added 4 gb RAM and 60gb SSD, total is around $450 for the hardware.


I'm hoping you experts on this forum can recommend a build for me that is as good as or better than this. What I am looking for my htpc:

- XBMC of course!
- primarily will be using it for 1080p mkv streaming over gigabit networked- unraid NAS (buiding at the moment)
- would also like ability to play 3D SBS, some light web streaming, but mostly just the above use
- bitstreaming audio (will likely install Windows because of this feature, but tossing around idea of just going OpenElec for instant startup)
- must be small form factor, mITX in a low profile case design, cool and silent
- Cost cheaper or around the same as the Zotac
- AMD / Intel - I have no preference but price matters and the capabilities must be met. This is the most clueless part I am dealing with - which CPU/Motherboard combo gives me the best bang for my buck?

Thanks in advance!
