You’re right, it’s a SFF machine (not USFF). No wonder they failed. Even the slim desktop version has 4 slots IIRC. Part of the problem is an inadequate cooling design, but the other part of the problem is that MCZ are just really sensitive to heat (not “plague” capacitors though). For an example (I’m sure you know this), in the HP DC5000 and D530 SFF computers, the MCZ in the VRM out are almost always bulging and leaking, often before any of the Teapos bulge, but the FL are never bulged.

But yes, improved cooling would certainly help the capacitors in these machines last longer.
