Speaking of off components... Can anyone make a recommendation for a UPS brand/model that isn't going to break the bank and that will support my PVR server?

The PVR server has a 400W PSU and 3 500GB drives in it. It's running on-board video and has 2 PCI video capture cards. I also need to protect and keep up, an external 2-drive RAID box (which has a transformer that I can't remember the load/current of right now).

My old UPS doesn't seem to handle the system very well. The battery died a couple of years ago and I fitted a replacement last year (identical manufacturer and part). It seems to beep at me every now and then and blinks some light. It's a smaller APC and I'll see if I grab the model number later. If the beep is indeed because the computer just pulls too much power, maybe I can still use this UPS for my router/backup drive (Apple TIme Capsule).
