I’ve reflowed every cap, now when i plug it the power supply will click rapidly unless the hard drive or floppy drive are plugged in

Does anyone know how to adapt an ATX power supply to this, I’m going to get the MAcTX power supply but i just want to verify that i didn’t damage the board while reflowing the caps
edit i just bought a picoATX 160, i couldn’t find the 80, is that okay?

Of course. You won’t be using more than 40W so 160 is more than enough!
If you used a standard iron (ie not a hot air station), nothing apart from the cap pads could have been damaged. If you really want to test everything, you can try to trace them back to a via or another pad but some traces may be hidden.
To be honest, your board is most certainly fine, the fact your PSU is clicking without the hard/floppy drives means it can’t maintain the proper voltages without a load. Yet another sign of failing output caps inside the PSU. In other words, the PSU is getting weaker and weaker.
Take your multimeter and check on the logic board’s PSU connector if there are any direct shorts to ground (and to other rails). Don’t use continuity mode. Anything above 3-5ohms is fine but your multimeter might beep for values under 35. FYI, on my Quadra 950, there’s about 30 ohms between 5v and ground, my multimeter beeps yet there are no shorts.

I got 21.5 ohms between the 5v rail and ground, it’s good to know my board is most likely okay, now where can I buy a mAcTX power supply?
