Yeah looks like a good pick on the PSU. I couldn't find a comparible PSU with that wattage/amperage at that price.
However, I recommend a different vendor (again). $6 cheaper ($11 actually, as there's a $5 instant rebate), plus save $7 on shipping. So you save $18 then you're only $2 over budget. :)
(I realize you don't take shipping into consideration on budgeting)
I didn't look at cases.
