Yep. Got one. Love it.
If 300W is enough for your needs, this will be fine.
<A HREF="http://www.pcpowerandcooling.com/maxpc/index_cases.htm" target="_new">Here</A> is a link to work out your wattage requirements.
I have 4 x 80mm Quietpc case fans, which use about 2W max total!
Now my system totals are 247W. Thats using the max numbers in the link. Assuming all my components are using the full 247W, I should really be using a 350W PSU. This allows the PSU to run at 70% or less, which is recommended for PSU life. I figure however, that if I'm already erring on the side of caution, I can take off 5W for each item I guessed at. This takes me to 205W which lets me use a 300W PSU happily.
