I am buying a new computer. I run OS X lion Server on my MBP, which I also use for everyday use. I was going to buy a Mac Mini Server + a MP, iMac or MBP. Considering the cost, I am wondering whether I can just use one computer, say a 6 or 12 core MP, and do things the way I am doing them now - in other words, is it bad practice to to use the computer that also runs OS X Lion Server?
