Firstly, your fairly new to TR, so on behalf of the TR regulars - Welcome
You didn't specify an exact budget, but striking a happy balance between performance and price I got this case 2 weeks back for my new build:http://www.zalman.com/ENG/product/Produ ... sp?idx=381
It's the Zalman Z7 Plus. I spent ages thinking whether I should get this or the tried and tested Antec 300 that was the same price. I finally settled on this because it's a little larger inside than the Antec, has more fans included as standard (and really quiet Zalman 120mm ones at that), and has that really nifty fan controller too, built into the side pannel. It's also got an anti-vibration base, hard drive mounts and motherboard stand-off's. I paid £44 for it - I would imagine you can get it for a price price your end just by swapping the £ for a $ symbol (Rather annoyingly!!!). It is a LOT of case for very little outlay.
On the PSU front, I would recommend this:http://www.corsair.com/products/hx/default.aspx
Speciffically, the Corsair HX520 Modular PSU. I use the 620W version of this, and it's been brilliant (as far as PSU's go). It's very quiet, has excellent efficiency and is able to keep voltages on each 12V rail perfectly steady. Finally, being modular (You really dont want to save the extra £8 to get the non-modular version of this) means there is no cable clutter - And loads of un-necessary floppy drive and molex connectors hanging around.
It's 520W output will handle your build, with room for expansion down the line and being able to supply enough juice for overclocking. I don't quite agree with axeman on the PSU front though. For me, this is a part of your system where you really should not
"cheap out". You will want a good quality PSU (Also consider Antec, Be Quiet!, Seasonic, OCZ, Zalman), that has solid parts and won't expire in a cloud of smoke - It's the only part that gives your PC it's power and regulates the voltages. If it fails, it could take some of your system componants with it. I picked up the HX620 for £71, so I expect the 520W version will be a touch cheaper.
Hope this is of some help.
