I used to have a 'Cube, but I didn't care for it so I sold it to a fellow HDer. He's been enjoying it quite a bit; not a bad system, per se, just didn't float my boat.
What, I can't be a fellow ACer? I only get to be a homey over at HD?

But yeah, I've been enjoying Rob's 'cube more than he did.
And either tomorrow or the day after I should be enjoying a 'box. Mmmm, Mechassault....
What do I have it all hooked up to you say?
Well I used to have a 36" Tosh. But as I'm sitting all of 7' away, the 36" was too big (could see the "cells" in the "Invar Shadow Mask" too easily). So I took back the 36" Tosh & got a 32" Toshiba Cinema Series that had better resolution than the 36" Tosh. And the damn 32" cost more than the 36" model...
Anyway the audio setup is this
Pioneer Elite VSX-39TX
Pioneer Elite M-10X Surround EX Amp
(2) M&K V-125 subs
(2) M&K S-125's for L & R channels
(1) M&K S-125C for the center
(2) M&K S-85's for the rears
(2) M&K Surround 550THX's for rear centers
I've got the 'cube hooked up via Component Video
The N64 & Dreamcast on S-Video
The 3DO, Jag, Jag CD, Super Nintendo, NES, Genesis, 32X, Genesis CD, Saturn, & PSX are all on Composite.
And I've got a Turbo Grafx 16 & Master System around here somewhere as well.
Almost forgot the handhelds...
Have got a Turbo Express w/TV tuner (the baddest handheld
EVER!), Nomad, Game Gear, & Gameboy Pocket.
