"Mac OS X, iLife, front row for under $800"4.0 starson by nekogami13
Pros: OS X, completely silent(except for combo drive), small size, digital monitor connection
Cons: Memory not easily user upgradeable(get at least 1 gb up front), integrated graphics
Summary: Ordered it as soon as it went dual core with a full 1 gb of memory.
Hooked into my monitor via hdmi without a hitch. Monitor model was recognized and proper resolution set automatically.
OS X runs perfectly, enough graphics oomph to play WoW-what more do I need?
