Technically I have a Dell Dimension 4100, however, it has all been pretty much upgraded at one point or another. Pentium III, 996MHz, 384 of RAM, XP Professional, 40GB and I use AT&T/SBC Yahoo! DSL.
Really, I'm not into fancy as long as it's fast enough for me to do my jobs. However last night after posting it decided it wanted to retire so I might be buying a new one tonight since it costs less to buy new than to upgrade and repair. I am on using dial-up right now, just struggling to halfway catch up on my work.
