This is my rendergarden. The floppy drives and CD drives are there mainly because I had them, and it was a place to store them. Once the OS and software is installed, they could have easily been removed. The stand is a $30 unassembled printer stand, with a cheapy keyboard tray bolted on. I haven't done it yet, but from my reading, a pair of medium sized battery backups will probably suffice for all 4 boxes, as the monitor is the biggest gulper of power, and I wouldn't be putting it on backup. For the garden I have, I run 2 surge suppressor strips; two because I couldn't find one that had 6 standard outlets and at least 2 outlets designed for power packs (for the KVM switch and the Linksys hub). Have I made any sense? I have not had my caffeine today....
