its just a basic design it looks alot better in my head lol

anyone?

I like where you are going with your design. I wouldn't put glass doors on it, just because it cuts down airflow. Also not sure if those are suppose to be wheels on the bottom but I'm guessing they are, make sure you don't use plastic caster wheels. They will break under the weight. Use the metal ones with bearings so they roll smoothly.

Something similar to these.

thank you and yes i was planning on using wheels (i move stuff alot) also i was thinking peg board on the back of the rack so wouldnt that be enough airflow?
