I've got a two bedroom apartment currently. Seriously considering a 3
bedroom place. So I can have a dedicated server room/office and a guest
room. Right now guest room serves as server room and living room is the
office.

Nice. Another reason that apartments are annoying. Limited mods.
Though one could make the mods and just patch holes when they
leave. I wanted to drill a hole to the outside at my apartment and
patch when we left. The wife said no. LOL. It's cool though, cause
she doesn't bat an eye when I mention buying a 72U rack. :)

Hmmm. Between racks you mean? Or from ports in wall to switch?

Ah yes. Power. This is what will drive me to a colo. I'm sure of it. I
don't want to rely on household wiring for heavy duty
loads.

Excellent. This is what I do as well. Though the PDUs that I picked up
don't work with my current wiring. :(

Nice.

Perfectly suitable for a wide variety of applications. Only things worth
swapping out on a regular basis are drives.

What kind of bandwidth in between?

Nice. I've not dabbled with Cisco voip at all. Just Freeswitch/Asterisk
(abandoned Asterisk and exclusively Freeswitch these days).

I believe this is the second mention of QNAP in this thread.

Excellent idea. Do you have a ramp of some sort to bring gear in?
