I would suggest that that you should get a model that has the UPS montering features. I think the BK400B is the lowest end that supports this feature. The power montering feature will allow your UNIX system to detect when the wall power has disappeared and begin an orderly shutdown. This requires a special cable that APC sell and upcd. I can't find the URL for upcd just now. I will post it later. Be careful when picking out a UPC from APC. Their sales literature is slightly deceptive. They make recommendations for which UPS you should buy based on power requirements of you machine however this includes the assumption that you are going to be connecting your monitor and laser printer to the same UPS. One should _NEVER_ connect a laser printer to the same UPS as a computer. When a laser printer starts up the power drain is enormous.
