I have a really basic set-up, but maybe it could be a 'base' for you to build something into. I use it as simply a bench for the most part. Got it at Home Depot for like $70 and it fits my needs well for storage/light work (not much of a power tool guy here).
On the other side I just have a storage rack. My garage is only 20x20 so I don't have a ton of room to work with, but so far it's gotten the job done fine.
The only thing "DIY" about this was the hours of assembly, but I just picked up this heavy duty sumbitch today at Costco. It's built like a tank and I love the fact that it's on locking casters, so it's easy to move when I want. Time for me to buy the long power strip I posted above and get stuff on the metal pegboard.
