Raven rigs to buy?

My friend built a rig to mine ethereum starting about 6 months ago. I gave him some cash and he built the whole thing I'm just taking a small part of the profit along the way…

My question is: Where is a good place to buy my own rig for Ravencoin? I know it's relatively simple to buy all the parts and put a rig together myself but I don't want the hassle. I'm looking for recommendations on websites or places to just purchase a rig I can hook up and start running right away. Greatly appreciate any and all feedback, thanks!!
