Finally, somebody who likes DAY GLO GREEN!!! LOL! Wow, thats a cool wood top and side cabinet; did you make it all yourself? Did you custom fab the casters and create a bottom frame; was this a requirement in your shop or make it easier to roll around versus the stock casters? What did you pay for your pro box and do you like it; does it have grip later drawers or dentents? Does the aircraft industry require the foam inserts to confirm tool security and eliminate engine damage? Sorry for the questions, you have a unique setup there!
Yes, I made the top and cabinet myself. The top is actually an old solid core oak entrance door. It was a 36" door, which left me just enough room to cut the door knob holes out. I took some 1x3" oak and routered it, then cut it down on the table saw so that it sat over the top. I love having the lip on there, it keeps tools from rolling off all the time.
The frame is 2x2x.25" angle iron, and 2x2x.125" square tube with 3/8" steel plates for the wheels, which are actually bending. I'm going to have to redo them eventually. They seemed to have work hardened themselves and stopped bending. The wheels are 8x2" Colson casters. They roll MUCh better than stock, go right over air hoses and power cords, and in 6 years that I've had it, I have NEVER had one screw or rivet stuck in the wheels, it just spits them right back out. In contrast, on my other Craftsman box, I had to clean the screws and rivets out of the wheels once a week.
The box ran me $1800. They were on sale for $2300, and I jumped on it. The first box I ordered, Sears sold to somebody that just walked in.
The second box had the same happen.
The Third box somebody had speared through with a forklift.
The fourth box showed up, and my truck was in the shop. A co-worker offered to help and meet me there with his pickup. I called Sears, and told them that we would be there at 2:30, and we HAD to be gone by 3:00. They said no problem. We show up at 2:30, and a semi is backed up to the dock unloading, and they say "oh, it should be done within 45 minutes".

At that point I completely flipped out. I called the District Manager and told him that the box WILL be $1800, it WILL be delivered by them between 2:30-3:00 pm the next day, the delivery WILL be free, or they can take their box and shove it, after I had waited 6 weeks for one.
It has the grip latch drawers, I love them. I'm not a big detent fan, and the Snap-On setup pisses me off. The foam isn't a requirement where I work, but I like it. It sure helps not to lose tools when you go through your drawers at night and see a big blank spot somewhere. Even my box at home is going to be done this way.
Nissan-crawler: wow, but i did not see any sockets in your toolbox ar airport?? why you dont like the orignal craftsman casters(6) on your box??
I think Nissan-crawler maybe lowered his box as to roll under the wings of aircraft, just a guess?
Yep. The 8" casters roll over things easily, and don't pick up screws or rivets. The frame helps keep it low, and also takes stress off the box. Even with a 2" thick top, and 8" wheels instead of 6" wheels, my box is 3/4" shorter than a stock one. It makes getting under wings and such easy, and it also makes for a great work surface height.
