I've converted my home office into my man cave/reloading room/computer room. A few photos to give you a sense of the reloading bench I've built to specifically fit the space I had available. It's currently sitting between my computer desk and two large filing cabinets that I use to store miscellaneous shooting/reloading stuff (e.g., powder, primers, bullets, ammo, targets, cleaning supplies, parts from guns, etc.).
The workbench came as a kit - the product is called "2x4 basics workbench kit". The kit cost about $70.00 and you can build it to pretty much any dimension you want. You cut the 2x4's and plywood to your spec. I used 3/4 inch plywood on mine for all of the shelves and topped my plywood with cork for the worksurface. The cork is a very durable and provides a nice surface to work on, but it stains very easily from solvents and cleaning the guns. In hindsight I should have used a dark stain on the cork to better hide the dirt and grime that it shows so easily.
Here is a link to the bench kit in case your interested. You can also google it to try and find a sale price on these kits. One nice things about these benches is once the wood is cut, they go together in a snap using long screws (included with the kit) and can be easily disassembled if you need to move the bench.
I've installed a press plate made by RCBS on my workbench. It allows me to easily change over between my Single Stage RCBS Rock Chucker Supreme, and by Hornady LnL AP press. Also it provides a very rock solid support on the work bench for the press.
One other image to show another angle of the bench. (My reloading room has gotten to be a mess in the last week)
The last photo in my line up is a stock image of the workbench kit you can buy to build the work bench.
