This is perfect for holding our computer servers. MUST be these measurements (60x24x84)
We need it to bolt/attach to the floor so it won't tip over no matter what.
Turn a 2x4 Ikea Expedit bookcase on its side. Add more units if you need more storage. It's deep enough to easily hold up to a 60" or so TV on top.

I'd say go for the ones with the varying sized cubby holes, but I guess they're not on the website anymore.
You can also get handy little boxes that fit into the holes, so that your actual games are tucked away.
This is just my preference/opinion on the subject.
Both types have their uses. If you have space for more than a single board, I would advise a mixture with more peg boards then slat boards. If you only have space for a single board then I'd recommend a pegboard because I find them to be more versitile overall.
The slats are good for hanging bins while the pegboard can be used to hang just about anything on it, depending on the type of pegs you buy.
I have these metal boards. They are rock solid feeling and I never have to worry about breaking them. Relatively cheap too. (I am not affiliated with this site, but have bought from them before).
I also have some old wood boards in my basement from the previous owner of the house but a lot of the holes are broken. I doubt I will ever need to replace the metal boards.

I actually have a workbench from the same company and it came with feet that allow you to easily secure it to the floor with a couple screws/lags/etc.
I would inquire with their sales to see if these are available for the shelving unit you are looking at, or if not, a similar unit.
