There's one very important thing I'd want to know before I make an recommendations; do you have a monitor, mouse and keyboard that you could use for this PC? I ask because if you don't have these it could quite drastically reduce what you can afford to spend on the PC itself.
I can also give you some good advice that applies no matter what. The first is don't skimp on the power supply, seriously make sure you get a good one if you don't you'll almost certainly regret it in the long run. Secondly made sure you get a Solid State Drive for your OS as a minimum but ideally get a bigger one you can install a few games on too. You will probably want a regular hard drive along side the SSD for document storage etc.
