xD --> cheap and good.
for case chose anything You like, I would suggest to get a normal ATX (4 5,25" drive space) type, for powersupply anything from 400 and above will do just fine. (well.. codegen NOT, never ever buy that. Neighter do mercury.) Get an LC power PSU, those are usualy good ones. (better than avarage, but still affordable rice)
what this setup knows..
Well, some gameing, offcource, and will work flawlessly for a long time. You can get vista on it, no problem. And won't LAG.
If -for some trange reason- it Would, just buy a fast CF card (anything from 233X speed will do) and plug it in, tell windows to use that to store swapfile.
That WILL do the job.
