this summer ill have a budget of about 700-1000$ for building a pc. i have a few cases, but im not sure if ill need a new one or not. my main concern will be how easily ill be able to update it in the future, a few years down the road.
id like to run 3 monitors off of it, one for weather, a wide screen for a band scope for ham radio, and one id use for general browsing and such.
almost everything i have now ive gotten from the dump or yard sales, but i think it would be fun to build something new.
can anyone point me in the right direction?

Thanks, I'll look into the sdr.hu stuff, and websdr.org is really impressive.
Regarding antennas, it says "A single horizontal wire at 1/4 wavelength will do." It certainly will not do well, you need some kind of 'counterpoise' (like the other half of a dipole) or some kind of ground connection. l/4 antennas are almost always vertical and have either radials or a ground plane like the body of a car with the antenna on the roof. There is no such thing as a one-terminal antenna like there is no such thing as a one-terminal light bulb...
