Two things I never ever cheap out on when building a rig is the PSU and motherboard. If I am given a budget that I cannot accommodate a proper PSU/mobo then I tell the 'customer' (this is not a business for me) that I cannot comfortably put together a computer that I feel good putting my name to. In these situations I try to tell them to get a pre-built machine.

At the end of the day, the low end machines are the toughest to configure for sure. If I do a poor job of it, I will just end up wasting my and the customer's time (and money). I refuse to support a machine built on a crappy foundation, and to me thats the PSU and mobo.
