Welcome to the forum and to reloading. Thanks for asking our advice.
I am interested in getting a Forster Co-Ax press. Saw on youtube that it can be stable and usable by just mounting with 1 C-clamp without plywood on a table. This is attractive for me as I lived in an apartment and SWMBO take offense to any items she deemed unharmonious with existing decor. The other features that I find useful is spent primer capture in a jar, she would flip if an errant spent primer makes it on the carpet.
Does the design of the Co-Ax minimalises leverage on the mounting surface? Would be it workable if I mount it on flimsy IKEA particle board furniture for instance? If this is indeed the case then it would definitely worth the extra expense over a rock-chucker I am considering.
The other thing I am interested to find out is if the Press can be pack down and stored in a 40mm ammo box, didn't managed to find any size information on the net. It needs to be neatly stowed away when not in use.
Very wise of you to plan your equipment purchases, both for appropriateness to your needs AND to maintain marital harmony.
Storage My press (and the board it gets mounted on) store in a plastic toolbox. Once you have a press, such toolboxes are available at most any hardware store for $10-15, whatever size you need. My arragement is one box for the press, one for the dies and one for all the powder handling gear, including scales, plus a few miscellaneous small hand tools. A folding workbench completes the ensemble.
When I started loading, I mounted my press on a 2x6 wedged in the drawer of an end table. It did no damage to the finish or to the drawer and since the assembly was tilted back a few degrees, made handling the process a little easier. I also used to lash the board to the top of the end table, but ALWAYS padded the top surface of the table with a towel or multiple layers of newspaper.
About leverage. Remember that the more leverage (what many call strength) there is, the less force there is on the mounting base. Also, the more spread out the mounting holes are, the less force there is on the mounting base. The advantage of the Forster (in this realm) is that no part of the press extends below the mounting surface. If you mount it on a short length of 2x6 or 2x8, the board can then be clamped (adequately padded) to any piece of furniture (or, better yet, portable folding workbench) with your "C" clamp. Note: If you do mount to furniture, using carpenter's wooden clamps will be safer for the furniture, though they are not as strong as cast metal clamps.
Dropped primers, spilled powder, errant dust losing small tools, etc can be adequately addressed by spreading a drop cloth as step 1 of setting up.
By the way, what do you load for? Rifle, handgun? What quantities? What are your shooting goals?

p.s. There are other presses that have spent primer handling just as good as the Forster, Lee Classic Cast and Lee Classic Turret among them.
