thin motherboard tray?

I've got a 4U 24-bay case that has a 1U redundant power supply setup in it. I may convert it to using a Norco 4U backpanel that I've got. But this would mean drilling for a number of motherboard standoffs (including some Xeon heat sinks). The current motherboard sits on a tray that's mounted above the 1U PSU setup.

The tray is fairly thick gauge and has bent edges along the left/right/front. I really don't want to get into sawing them off. Now, if I had a bandsaw with a metal blade, sure... but using a dremel on this much material isn't happening. I don't need it THAT bad to put up with changing THAT many broken cutoff wheels...

Yes, I realize I could kludge it with some plastic standoffs and a backing plate for the heatsinks. I may just go hillbilly on it, but I'd prefer to find a better way, if possible.

So, before I go down that road I'm curious if there's a generic sort of ATX motherboard tray out there. Does anyone make just a flat sheet of metal that's pre-drilled for the various ATX standard mounting points? Something with counter-sunk holes for attaching the standoffs. This would let me avoid putting a lot of holes in the case. No doubt with a few in the wrong places, of course). I've already dug through my graveyard of obsolete machines and don't have a suitable tray.

Along these lines, does anyone make a PDF of the ATX mounting holes? Or a printable template of them? This to save me from getting it wrong, several times...
 
I gave up on finding one or cannibalizing something else. Instead I mounted the motherboard to the back window panel, secured with some PCIe cards screwed to it, and then used some tracing paper to mark the holes. Both for the motherboard standoffs and the back panel screw holes. I then removed the standoffs from the motherboard and used a mechanical pencil to trace the holes. If you extend the lead from the pencil about an inch you'll have enough to effectively trace the holes. I did that to confirm that the traced holes were in the right place too. Worked great. I've yet to securely mount the motherboard as I don't have any female-female standoffs on-hand. But when mounted to the back panel by cards it's pretty secure. At least well enough for now.
