The cost will mainly rise with the UPS's power capability and its autonomy 
(ie. the length of uptime during a power failure). Get a UPS as closely 
matched to the power consumption of your PC as possible  (but greater, 
obviously) and then decide how much autonomy your require ie, decide if you 
want to try and keep the thing running for an hour or more in the hope that 
the mains power will be restored or decide if you just want 5 or 10 minutes 
of autonomy to span any very short interruptions and then do a graceful 
power down. Not sure how linux implements UPSs but most UPSs have a serial 
port connection so it should then mainly depend on the linux UPS app that 
you use.

PS Don't bother powering your monitor via the UPS, just the linux box 
itself (sorry if that's stating the bleedin' obvious)

I'm sure the guys who live and breathe linux can help more on that side of 
things but I hope my suggestions are of use to you.
