You will probably find it difficult to get a web control panel set up on your server. Windows Home Server already has a web site built in, the Remote Access web site, and you would need to work carefully to avoid damaging that functionality while installing
a control panel. In addition, Windows Home Server is not licensed for hosting/serving arbitrary web sites, i.e. it's not designed to be Windows Server "lite", so you would probably be violating the EULA as well.
I highly recommend you download Vail, read all the documentation carefully so you will have a better picture of what Microsoft intends it to be, and especially read over the list of known issues (which is rather long for this build). Give it a try and see
if it's what you want at home.
I'm not on the WHS team, I just post a lot. :)
