I'm looking to do the same. I picked up a side out rack from Middle Atlantic off e-bay for a pretty good price. My plan is to mount it inside a cabinet that will be in my "media room" and is where I have all my cabling coming to from all over the house. The suggestion above about labeling the panel is excellent and is the way I'm planning to set things up. I'm also getting ready to build the Hybrid/Core that will sit in the rack, so I'm looking at picking something like this up;http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150519438421&ssPageName=STRK:MEWAX:IT
If you have a spec on what you are building for your Hybrid it would be helpful to know what it is as I am not seriously into computers and the amount of options and choices available have my head spinning.
I also picked up a rack mounted switch and POE injector for my IP cameras. I've tried configuring them with Zoneminder before MCE is set up, but that has proved to be rather difficult.
looking forward to any info you have to share, when I get the rig assembled I'll get some photos...
