With summer here, I'd like to cool my IT "cupboard"-type cabinet at home. It's around 1.5 x 1.5 x 1.2 meters (W x H x D) or just roughly 3 m³ in volume.

All equipment (3x servers, switch, monitor, AP, and other ancillary components) consumes around 250W, ±20%. That roughly translates to around 850 BTU/hr of generated heat. In fact, just within the month, one of the servers which is installed quite near to the ceiling crashed showing an amber health LED indicating that it has preemptively shutdown due to overheating. Moving the server is not an option so I will have to cool down the whole space during the summer.

I am looking into designing a small A/C out of automotive A/C components. Does anyone (or do you know somebody) who has ever succeeded in fabricating such?

why car a/c? afaik your typical car a/c compressor is a lot more powerful than a typical window-type a/c. why not just rig up a small 0.6HP window type?

or do watercooling for the processors
