Amplifiers?

Here's some more reading on amplifiers, and "HiFi Mysticism" http://www.diyaudio.com/forums/showthread/t-12752-p-6.html http://www.audioasylum.com/scripts/t.pl?f=general&m=311853 Both sites are great for all sorts of information on HiFi, from both subjective and objective camps. Personally, and all other factors being equal (Good quality components, not state of the art but not broken designs, either) I find the factors affecting the sound break down like this: 40% speakers/room accoustics 50% source material 10% everything else (system components, AC quality, etc...) Keeping things quasi-on-topic, I've decided it's time to build a show system, with blinkenlights and excessive switches and knobs and everything. I've settled on the AOpen AX4GE Tube-G motherboard, if for no other reason it's probably the first computer to have a tube on the mainboard since the UNIVAC days. I can't find where to buy these beasts, however, so does anyone know where to find maybe 1-2 year old computer surplus or closeouts? For further retro-fun, I'm planning on putting in a POST code analyzer with big LED display on the front of the case (ala IBM RS/6000 systems), one of those retro-looking fan controllers, and Corsair XMS memory with LED status indicators. Window on the side, of course :) Then I'll run Linux on it with hercules and a fullscreen 3270 emulator plugged into OS/360. It'll be fun to run at lan parties :) PS: My system- Sumiko turntable, Sonic Frontiers Line 1 preamp, NAD 214 amp, Audio Alchemy ACD1 CD player, Denon DVD-1600 DVD player, Magnepan MG-1.4 speakers, homebrew phono preamp and AC filters. Almost all used, sounds fantastic.
