Nice work there Knightsword!
I recently upgraded to a newer Mac 'cause my old Power Computing PowerBase 240 died on me after many years or good service. The old towers are pretty big! Lots of room for stuff.
I used to own an Epson Color 2 printer that also held up really well... that is until they stopped making the ink carts for it! Which I found out recently when I ran out and went on a whole town search for one. Nope. No where. I had to order one online and then he whole printer decided to call it quits, just like the computer a few days earlier. So, I bought an HP printer combo thing that I really love. Now I can ditch all of my old SCSI stuff (that weighs a ton) and move on over to USB land like the rest of the world.
How big is your monitor? I don't know nothing 'bout video cards... does the Radeon allow a 21" to run in millions? Just curious.
I have been running OSX fo a long time now and I love it. Rarely crashes and if a program does decide to freak out it doesn't take down the entire computer. Hey! It's a new feature for us Mac guys!

hehe.
Have fun with your "new" set up!
