A working Pro Tools LE rig for $75? Yes, and it's super stable and ready to work now.
It's an Apple iMac Core Duo 17" 1.83 GHz, 4,1 A1173 160GB HDD. Maxxed out at 2GB of RAM. Has an Apple Superdrive built in, for burning DVDs and CDs. I listed it as a Mac Mini because it is essentially functioning as one currently, hence the cheap-o price. It works great, but the display is shot. The only other issue is that the power button takes lots of pressure to turn on the computer. I'm including a VGA display cable that lets you match it with your own external monitor (not included), kinda like a vertical Mac Mini. Also included in an Mbox2 interface, with analog, digital and MIDI I/O. Super compact, and sounds great.. Includes original keyboard and wired optical mouse, although the kb is not working currently. I have another to test it with, though.
$75 cash takes this system, ready to rock. But if you need more inputs and flexibility . . .
Substitute a Digidesign Mbox 2 Pro, with word clock and more I/O, add $25
