I have the IONITX-D-E, 90W Pico PSU with 60W brick power supply, 30GB SSD, 1 x 2GB RAM (not dual channel), Windows 7.
I use the M350 case, looks like this:note: this is not my build, but a similar looking one from http://www.avforums.com/forums/home-...otac-n330.html
I would have gotten the IONITX-A-U though because the included 90W PSU is more convenient and cheaper than a Pico PSU.
All the parts including the factory IONITX CPU fan fit in very easily with room to spare. No hacking and modifications needed. I built the system in 20 minutes and I've never built a PC before. I copied the contents of a Windows 7 installation CD onto a USB drive, plugged it into the USB port, and it started installing Windows 7 immediately upon computer-startup. I did not have to mess with BIOS, not even the USB boot settings.
It plays 720p movies very smoothly. It plays several 1080p movies perfectly smooth too (30-40% CPU load I think), EXCEPT for 13GB 16.2 bitrate 1080p file. It's very choppy (unwatchable) with 90-100% CPU load. I haven't really checked if hardware acceleration is active with this video, nor have I tweaked anything yet.
Has anyone been able to play such a 1080p beast on their IONITX-A-U or IONITX-D-E without issue? Should I bother messing around with codecs or will it be a waste of time? Has anyone determined the max. 1080p bitrate the dual core IONITX board can handle?
Overall I'm very happy with this HTPC. I had a large HTPC with micro ATX motherboard but I wanted a small mini ITX box with low power consumption and I'm very happy with the IONITX so far. It played several .MKVs I threw at it without complaints, except for that one rare 16.2 bitrate 1080p.
