I thought this might be an issue. I do have some older 10Gb HDDs that are
probably suitable, and some 40Gb drives that don't heat up too much. I
may, however, just buy an external drive for the craic.

It'll be in a pretty central point in the house, so as quiet as possible.
I guess with an external drive the smaller PSU should suffice for the rest
of the kit.

Graphics isn't an issue, but SSH is. Thanks for the info.
