Yea it is, at the time i was torn between spending a little more and getting the 400r but im really happy with the 300 plenty of space and airflow.
I have the same desk but mine has a tray that the keyboard sits on. good job on the cable clean up!
Mine did have that but my chair was too big so took quite a few things off including that.
I got it at office depot or office max, one of those places. and yeah my chair hits it too, but i threw some 2x4 chunks under the wheels to get her up just that extra bit i needed. did yours come with the shelf system as well?
What did you use to clean up the cables? Anything special or just cable ties and some creativity?
