You might also look at a proprietary PoE solution, or maybe regular 48v PoE
with a DC-DC (48v to 12v) convertor on the end. You could also look a
solar.
FWIW, there is a 60 watt injector available (Mfg Part #: TR60A-POE-L) :

They make ATX power supplies with DC inputs, but I don't know if PoE can
pass enough wattage for them.
Have you seen any of the RB announcements?

Hi,
Now you are understanding what the rest of us have been going thru for
the past couple of years. ;)
The RB532 is underpowered for big backhaul links, yet any of the
mini-itx or micro-itx boards need 120VAC or a seperate power cable and a
power converter inside the box. Running LMR cable works for short runs
(20-30ft), but after that it just limits the signal too much.
What we really need is an 800mhz Routerboard in the same form factor as
the current RB532. :)

I have been doing some research and these seem great, almost. The main
problem I have is power where it needs to be. If I could get 120v then
I could easily use one of these units or a standard PC. Most of my
sights are on water towers so there is no electricity at the top of
them and the radio ahs to be feed with PoE. I have tried putting the
radios lower and using LMR cableis to the antennas but have had bad
experiences with that in the past.

recomendations/experinces with any in particular? Do they support the
MikroTik RouterOS?
Just get something fanless and low-power, and you're good. I usually
suggest "fanless" because you can get the whole No Moving Parts
assembly, which means fewer things that can break; the benefit of that
should be obvious :) Low-power is optional, but usually goes along
with fanless, because otherwise your computer could cook itself.
The biggest downside is probably the "some assembly required" bit -
you're basically buying all the parts for a small desktop computer,
and assembling them yourself. There's a bit of learning curve even if
you've worked with desktop PCs before (those power supplies especially
are tiny, and can be annoying to work with). Your first system will
probably take an hour or two to assemble.
It will be a bit bigger than a Routerboard 500 - probably six inches
square, two or three inches tall. And you'll need "real" power, as you
can't usually run these with POE.
RouterOS is available for "standard" x86 hardware, which most mini-ITX
boards would be.
You may also want to look at the new Soekris 5501. I haven't tested
RouterOS on it, but Soekris is standard x86 hardware, so problems are
pretty unlikely. It's a single-board unit, so you don't have to
assemble anything; you'll be getting a bit less performance at about
the same price, but you don't have to spend an hour putting bits
together.
mini-box.com has a good selection of bits and pieces; I've bought from
them before and they took good care of me.
