When I have the parts, and I have the time to do the mods, it will be the first thing I do
Meanwhile, here's pictures to visualize the ideas:
I've done some measurements, and it seems like the PSU can be moved about 1.3mm-1.5mm to the side panel (depending on where you move it).
There's room enough of the backpanel for drilling 3-4 holes for PSU mounting, but I will possibly have to move the PSU slightly down for maximum clearance.
I'm pretty excited about doing this mod, so I can see if the Big Shuriken 2 + XT140 combo will work! The Big Shuriken 2 with a XT140 is about 59-60mm tall, depending on how well it mounts. But there is a problem.
AS you can see, there is some small part on the edge of the fin-stack that sticks out. This has to go, so it's time for a cut and file job:
The final result is pretty good. The Raijintek Aeolus Alpha used here is comparable to the XT140, as it's also a 140mm fan in a 120mm mounting position, and both are 13mm tall. However, my Aeolus Alpha makes a really annoying clicking sound.
Also, I just picked up an A9x25 fan. So before I make my PSU mod, I'll test this baby out. I'll wait untill I have my Enzotech RAM- and Mosfet-heatsinks, so I can mod my motherboard, because this mod will allow me to orientate the LP53+A9x25 in any direction I want, whereas now, I can only mount it with fin-stack perpendicular to the RAM sticks, which creates a heattrap. I suspect my stock C7 cooler in optimal orientation is better than the LP53 in a suboptimal orientation, as they're both all-copper heatsinks, and while the A9x25 is definitely better, the total clearance of free, "cool" air will be higher for the stock C7 (48mm vs 53mm), so there's some cancelling out effects there.
Also, I have zero faith in the stock screws for the LP53. So I'll be fitting my LP53 with either the C7 backplate or the Big Shuriken 2 backplate. I expect both to work. Here's the stock screws with washers for the LP53:
Compare those to the backplate of the Big Shuriken 2 mounted on the LP53
As far as I can tell, the washers on the stock screws and the backplate of the Big SHuriken 2 is about the same size, so I suspect the backplate is compatible with the LP53.
