Everything looks great....except that PSU. You get what you pay for, so check out Antec, Enermax, OCZ and PC Power & Cooling to name a few.

Check out reviews at various sites such as tomshardware.com.
 
actually thats one of the beter "affordable" supplies he could opt for
of course you should apply a derating curve to it
strangely unlike most manufacturers FSP actually publishes a derating curve :p

2W / C° from 50C° to 25C°

youll drop 2 watts for each degree rise in temperature above 25C

Id say keep the supply and buy a UPS :)

theoretical
http://takaman.jp/D/?M=PbQAQbdHhSASjiH3kG5H5ZavPCMZ&english
realworld adjusted to say 16A +12V 240Watts
(even that is likely high for a worsecase given a single videocard I gave it the full 6.25A\75W +12V)
well within the capacity of that supply

you should have a comparitble crossload to its big brother
http://www.xbitlabs.com/articles/other/display/bluestorm_5.html

so go up 47.5 to say 30W and over 100 to say 200W on the chart and then back down to near zero and it looks like your very likely in the 1% to 2% load regulation fluctuation band (+12V)

you can get a tighter and cleaner supply, but you likely dont need it or want to pay for it :p
(also "brands" arent always a good indicator, some may well be looser and dirtier than that one)

all in all given the load and probable use its coming in exceeding spec
the +5V rail is a little dirty but still in spec and besides you vidcard runs off +12V as does most everything else and its an ATX12V v2.01 compliant supply with dual isolated +12V rails

PS Tomshardware doesnt know Jack about PSUs
(they are just fanastic at blowing one attribute completely out of proportion)
rely on Oleg @ Xbit, Mike Chin @ SPCR, jonnyGURU@SLCentral and Lee Garbutt (RoboTech) @ PC Perspective\systemcooling ;)
 
All looks good except for the case. You will need many fans inside that little case to keep those components cool, ESPECIALLY if you overclock.
 
I picked Fortron because they make cheap + good PSUs. I realize that you get what you pay for, but a $50 PSU from a good vendor should be good enough for me.

As for the case, I have no problems modding it to accomodate more fans if the temps get too high.

Thanks for the replies and keep em coming!
 
Other than agreeing with what others have said about your PSU, you need to consider buying more RAM. In fact, 2GB of RAM, period. You said yourself you will use this machine for gaming and video editing. Don't sell yourself short with 2x512 sticks.
 
Ah, Durandal beat me to it. ;) 2 gigs of RAM is the new standard now-a-days. I'd definitely spend the extra mula for another gig.
