I'm about to install SCCM 2007 R3 for the first time in a clean site. We've never used it before and I've been doing a lot of reading and research before doing anything. I'm on a external week long training course soon too. However one thing remains unclear, should I host it on a x64 or x86 server? I've been seeing issues running it on a x64 server, managing x86 clients. The installation doesn't seem particularly slick either if you move to x64 host.
So, what is the deal in the real world? It is a pain to install and manage? I'd appreciate any feedback.
