This thread is old but if you are interested I have a Dell server with 7 tuners,3 antennas, 5TB storage and 4 Xbox 360. Works fabulous but I did not start out this way. I Started with a clone pc, 1TB and 2 tuners one antenna and Xbox. First off use cat 6 GB networking, wireless does not cut it here. Secondly you need one CPU core per extender or it will be choppy. More tuners prevents the ‘no tuner message’ min 1 per extender. Great to have a program guide just like sat or cable.
