It should be no problem to use whatever MB/CPU combo you would like. Shouldn't need more than 4 gigs of memory, if you're filling up the buffer then the settings for the video should be tuned down. I think faster clock speeds are better than more cores, but that could change with live streaming (where multiple encodes are going at once). > On the bright side, I have a PV-350 that I'm re-purposing from an > old mythtv setup :) Just be warned it's a high heat card.

One of the goals of the system was to produce low heat, so we picked that chip because it's only 25 watts. Also, the PV-350 is a bulky card, so picking an enclosure that fits it well (esp. if you have a high heat sink) is important. Finally, we recommend a certain power supply that aimed to minimize both heat and space, this might not work best for you if you get a beefier system. For a single "one off" testing box not much of this matters, but if you wanted to deploy 20 of them then you want to consider some of these with respect to your classroom setup. > Along those lines, we're considering for cameras either a Sony > EVI-d70 or EVI-d100. Any pro's or cons for either? I know nothing about cameras, but we use the SNCRH124's from Sony. http://pro.sony.com/bbsc/ssr/cat-medicalproducts/cat-medicalcameras/product-SNCRH124/ I think we have one of the EVI-D70 series of cameras in deployment as well. Hope that's helpful!
