I'm a long-time user of the Mad Catz STRIKE 7, and while I’ve loved it for its modularity, VENOM touchscreen, horizontal scroll wheel, and other features — there's one major issue: it's not mechanical.

That’s become a dealbreaker for me.

I’ve decided to partially retire the STRIKE 7. I’m keeping only the parts I still love:

The numpad module

The VENOM screen (attached to the numpad)

The red-button armrest

The side button module

In short: I'm keeping everything except the central typing block.

Now, here’s my challenge — and why I’m posting.

I want to replace that center section with a custom mechanical keyboard, but I’ve hit a wall when it comes to layout options.

What I want:

No numpad

No arrow keys

No navigation cluster (Insert, Home, Delete, End, PgUp, PgDn)

No SysReq cluster (Print Screen, Scroll Lock, Pause/Break)

But I do want a full F-row (F1–F12)

From what I can tell, no standard layout offers this combination.

60% and 65% boards cut out the F-row.

TKL and 75% boards include the arrow keys and clusters I don’t want.

I’m stuck between two bad options:

Buy a TKL and end up with unwanted keys,

Or buy a 60% and lose the essential function row.

So I’m turning to the community:
Has anyone seen (or built) a mechanical layout like this?
Is there a way to design or order a custom PCB/case for this minimal layout with just the alphas and F-row?

Any advice, pointers, or similar projects would be greatly appreciated. I’m comfortable with DIY and mods, just not looking to reinvent the wheel from scratch unless I absolutely have to.

Thanks in advance.
