The picture has a bit of glare, but this is most of my collection:
On the top shelves I've got complete/partial sets along with actual shoeboxes (not the "shoebox" storage boxes) containing supplies as well as odd-sized stuff like graded cards and jumbo cards. Oh and also one actual pair of GU shoes, just so they can be used for their intended purpose.
On the left there's 4 shoeboxes (card shoeboxes this time) containing lower-end inserts and nicer toploaded cards like autos, patches, and super low-numbered stuff like plates from my baseball collection. Cheaper GU/autos and tough but not super tough inserts fill 8-10 binders in the black drawers to the left. Below my PC stuff are 3 3200-count boxes containing base and <$10 inserts for trade (all inserts penny-sleeved) in alphabetical order. Then there's a shoebox containing RC's for trade and another one full of toploaded GU, autos, and $10+ inserts for trade.
Below that row there are 9 3200-count boxes holding base and really low-end inserts of baseball players that I think are "good" but the cards are so cheap I don't put them on my trade site. There's another 5 of those for football. All alphabetical order. This spills into the bottom row on the right side, which also has shoeboxes holding some of my football collection (not seen because of the giant sorting mess on the floor). The second row on the right has 6 3200-count boxes containing base and low-end inserts of guys that have played for the A's at one time or another. I have another 1-2 boxes that need to be sorted in, which explains part of the mess. The next row up has 2 more big boxes of football cards for trade along with a couple of binders, one of which holds my partial 1988 Topps autographed set (about half done at this point).
The second from the top row on the right has my Trent Dilfer collection - a binder with every base card; 2 shoeboxes completely full of inserts in 50-card cases, toploaders, and screwdowns; a little 400-count box that holds graded cards; 3 actual shoeboxes holding odd-sized cards, promo sheets, magazines, videos, and other memorabilia; and a 2001 Absolute Signing Bonus Super Bowl XXXV Mini Helmet just sitting there.
My dirt commons are in 3200-count boxes and various other boxes in the closet.
My 850+ video game collection is way easier to organize, it just goes on 2 gigantic CD/DVD storage shelving units against the wall.
