I like the sawhorses. Seriously.
My home office room, which is now pre-wired up like a Borg Cube and has some new hardwood flooring in, is still undergoing some cabinetry and lighting work. After 13 years of professional development and global projects, I decided I wanted a place to work that...works. After a while you start to realize how much of your waking life is this stuff.
The old room was carpet and dim and cold and...basically nothing that ever made me want to sit in front of a PC after...sitting in front of a PC all day at the commercial office (in an commercial space that is grey, and cold, and dim). Since I work remotely some of the time, and study here, I'm partially investing in my career development. But y'know...with all the gear halfway there, why not some cool fun stuff, too?
Dabbling in all of it makes you a better informed techie, after all. I got to where I am starting with a PC when I was a kid...mostly trying to get games to run and adding hardware upgrades for...games.
