Mac Mini Server... Can I wipe it clean and use non-server edition? As the title says. I have a Mac Mini server--I bought it because I liked the lack of a optical drive. I don't really care to use the software, and now having to spend an additional $50 on Lion's "Server" add-on is meh. 

Can I wipe the machine clean and install a fresh 10.7, non-server edition?
Yes.  I am currently using a late 2009 Mac mini Server with both Snow Leopard and Lion (non-server editions).
