Well,
I own several Macs actually.
RIght now my main workstation is my G5 dual 2.7 Ghz (2.5 Gb RAM) with Logic 7 Pro and MOTU 828 Firewire interface.
Motif ES for a controller and some more hardware synths to mess with.
Hard disk space wise I'm just over 700 Gb free space total. Recording at 24 bit 196 k because I can. :

My "middle" Mac is a G4/933 Mhz (1.5 Gb RAM) hooked up to a Digidesign Digi 001 interface. Used to run Logic Pro on it as well but right now my wife took over that machine and uses it for on-line banking.
Although I did install Absynth on it last night. SOmetimes it's cool to mess with synths while having breakfast. My G5 is in the basement and I'd rather be upstairs with wife and kids while their getting ready for school. You know, being too lazy to go downstairs. LOL

THe oldest of my Macs is a PowerMac 7100.80mhz. That's got good old Digidesign session + TDM cards all connected to a Digi 888 interface. Mostly TDM processing but I use Logic 3.0 as a front end.

My main concern now is building a vocal booth.

Mind you none of this shit even remotely compares to my TL or my 335. You know the feeling.
