PC power supplies require a minimal load to source output voltages inside the specification range. Some will check if a load is connected and switch off outputs with no load. So each of the 3.3, 5, and 12 V rails should be connected to some kind of load.
For the 5 and 12 V rails I would use an old drive (floppy, CD/DVD, or hard disk). The 3.3 V rail can be connected to a load resistor (e.g. 3.3 Ohm, 5 Watt). Finally you must connect the Power On signal (Pin 16/14 for ATX-24/-20) to GND.
It might be necessary to connect an additional load resistor to the 12 V rail because the load may be not enough when the motor of a conncted drive is not running.

I've always just used an ink-jet all-in-one and called it good. I used to buy HP, but the materials seem flimsy now, so my current device is from Brother. There are some things that just aren't worth spending a lot of time thinking about. Go to a store that has a bunch on display and choose one.
Unless you foresee a change in line technology, I'd go for a combination. One less box to worry about. I have had a couple of ADSL modem + 4 port router + wifi boxes, and they do just fine. 3 wired ports in use and about 6 wireless devices. Whatever you get, make sure you lock down the admin access.

Go for the two in one option if oyu have a choice.
I don't have a choice as my ISP provides me with a fibre router(fibre cable in and one cat5 out) - I run a router/gateway off that.
My main computers then run off the gateway via Cat5 and I also have the wireless, on the gateway, switched on so that I can use mobile devices around the flat.

I look at the specs on various motherboards, and don't see anything about the number of monitors they will support.
A low-end motherboard will usually have onboard video capable of supporting one monitor. However, higher level motherboards will not have onboard video. For them, you must purchase and install one or more graphics cards.
The difficult we do right away...
...the impossible takes slightly longer.
Motherboards normally only support 1 or 2 monitors, one on VGA and the other on some digital. If you're going to run 3 monitors, seriously, forget on-board video. It usually sucks ass. You're going to get a separate video card.
You start with which CPU you're going to run, then you go to the motherboard and RAM. Which one you get depends on what you're going to do with the thing and whether or not you're going to tweak the chipset to eek out every bit of speed you can get.
On my rig, I have an Asus P8-P67 motherboad and run dual GTX770's, and (3) 24" monitors.
I am no expert in these things. But I do know that I can read such properties from the Networking interface, or from the Device manager (if you're having Windows). Otherwise, you can always check for the Mac address for your own system (Read the manual?)
