to mine other cryptocurrencys it's a more complicated affair, if you like to solve problems then it's ok for you. Just look for the thread that talks of the 10$ plastic case and it will tell you how to build a well ventilated case for your computer farm.
with 5000$ you can build 4 computers of 3* 7970 cards each plus mobo cpu ram hd and case each. Look at the hardware thread ans you'll find one with the basic starter kit.

Me I mine with my old GPu and maybe i'll buy a 7950 or 2
