Need recommendation for minitower and for soundcard

#1
I have a standard (ATX I think) motherboard, ATA drive, and CPU and
fan.  I need a mini-tower (or smaller) to put them in.

something with a power supply, approx or under $70, looks at least
somewhat elegant (not a gamer ultra visually loud and obnoxious
looking case).

The small the better, but it needs to fit a standard motherboard and
be easy to install the components into.

#2
I also need a soundcard for this system.  it will be used to play MP3s
into a stereo system, and the onboard sounds doesn?t sounds good at
all.  Under $50 would be good. Must be easy to install.  just need
some clean audio, no fancy Dolby or other high end features. No
gamming stuff, no DVD or surround stuff. doesn?t need to be audiophile
quality, just something as decent as a $60 CD walkman. RCA jacks would
be a plus, but only if they can be had for under $50.

just send me links so i can buy online.

Thanx in advnce

Although with budget to spare you may consider upgrading your MainBoard. :)

I use this company consistently as a specified vendor at my job.
www.pricewatch.com is another place if these prices aren't low enough
for you :).
