It would be good for a laptop and pretty much nothing else. Those small inverters have a nasty habit of self destructing when over loaded. Besides for the money you're going to plop out for that set up you can get an APC BX1300 LCD from Office Depot ($159.00usd). If you're wanting to support 5 (4 + the one smooth wall is running on)computers and 4 or 5 monitiors, you should go larger. And the price goes up. Or get 2 of the UPS's and spread the load.
