An uninterruptible power supply (UPS), also known as a battery back-up,
provides emergency power and, depending on the topology,
line regulation as well to connected equipment by supplying power from a
separate source when utility power is not available.
It differs from an auxiliary or emergency power system or standby
generator, which does not provide instant protection from a
momentary power interruption. A UPS,
however, can be used to provide uninterrupted power to equipment, typically
for 5-15 minutes until an auxiliary power supply can be turned on, utility
power restored, or equipment safely shut down.

What you need is a Power generator to supply power in the great outdoors
where plug ins don't exist or some sort of converter to run
off your Car/Van/Camper system. Maybe if you told us the setting your going
to ??
Laptops can be bought with RAID1..it just requires a longer search or custom
build job. They can run up to 8hrs off Battery and can be
recharged by means Car/Van/Camper converter also by means of Solar Panels
that are now on the market.One Piece design easily transported
Desktops consume more power can easily be build with RAID 1 but if taken
into the great outdoors either need a very long extension cord,
a car/Van/Camper power converter or a freaking Electric Generator which
usually requires liquid fuel (diesel) to run.Also needs the Monitor.keyboard
Mouse to be transported.

Maybe you should be looking at the use of the system while you are wherever
your going and build/buy according to the minimum you need
to do whatever your doing??

Wether it be a Laptop or that thing your thinking of building in order
for any of them to be on
all nite they both will need POWER...from a wall plug in and as such a
Laptop will do it and have the added
benefit of running of battery when power is not available.

I would probably but a UPS locally designed for place I'm at; if it comes
to that.
A laptop is out of the question - for the (computing) power I need I would
end up spending $3,000 - not an option.
I'm also looking at a Mac Mini - but I don't think I'll go that route.
