Do I take the shroud off and just have the fan there to have access to tighten the hotend?

2. Could someone recommend starting hotend and bed temps for ABS?

3. What screw sizes are used to mount the haswell type power supply, the M3's are too loose so I am suspecting they are not metric.
1. Yes, any all metal hot end should be tightened up while hot. This will help ensure that joints remain tight (and leak free) as the different metals (brass nozzle, aluminum block and stainless steel barrel) heat up. So yes, take off the shroud for the bit of time needed. On my latest rebuild, I tightened things with the hot end loose on the heat bed.

2. The few things I've done in ABS have been at around 235 degrees.

3. I'm not familiar with Haswell, but most of these supplies are clones of Mean Well, which use M4 mounting screws.
