SOLD!
I upgraded both of these, so they need to get the heck out of my shop. The large red box is a U.S. General from Harbor Freight. It usually runs just under $400, asking $200. It's not the giant one, but it's expandable for reasonable prices with top and side cabinets.
Tool Cabinet
The service cart is black with 4 drawers and is almost always on sale for $110. Asking $75.
Service Cart
Combo price of $250 for both, and I'll deliver in Reno/Sparks if you don't mind waiting for me to have a day off... which might take a while. Also, tools, parts and general detritus shown in the pics is not included, unless you really need some of it more than me. Which is likely actually.
