Doesn't look like $300 gets you much. I'd say:
$98.05 CPU: Intel E5200
$65.87 MBD: Gigabyte GA-EG31M-ES2L
$39.99 RAM: Corsair XMS2 2GB 2x1GB DDR2-800 modules
$116.93 CASE\PSU: Antec Nsk 4480B II w/380w PSU
---------
$320.84
That motherboard only has two RAM slots in it though, so if you want to upgrade down the track you'll have to throw that RAM out and get new ones. You'd be better off getting 4GB for an extra $40 or so, but if your budget is tight I guess that's all you can do.
There are cheaper case/psu options as well but ones I've never heard of. Cheaping out on a case is never worth it, especially if you're building it yourself. You might want to check here http://extreme.outervision.com/psucalculatorlite.jsp to see if the PSU is enough for you too, depending on what else you're going to put into it.
