tmux with weechat and telnet.
old android phone that I rooted.
my current PC
ASUS Pro Gen3 with Intel Core i7, Corsair Hydro Series H100iGTX Cooler, GeForce GTX 780 graphics, and 8 gigs of DDR3 RAM (goes up to 32 gigs) so I plan to add more in the future.
This is simply an old android phone (Samsung Infuse) no longer in service that I rooted and created a custom theme for. I use it as a portable media device and have a terminal app installed so I can log into my linux server for monitoring.
