Looking for help desk software to run here

In a previous job I had setup and used Liberum Help Desk and I quite liked it. Now I need something like that I can run from DreamHost. Does anybody know of a help desk app I could install here? It needs to be reasonably easy to customize since I’m really more of a Windows guy.

Thanks for the suggestions.

You might want to take a look at my companies product, HelpSpot Help Desk Software. I believe we have users on Dreamhost and a few years back we used Dreamhost accounts for testing so it should run fine. It runs pretty much anywhere PHP runs.
