Yah... the HD mounting need to stay.
I was thinking about something simular to the original PCU case though a bit shorter and the corner "cut off" to allow a fan (lownoise of cause) to draw the air at an angle into the PCU and then out the back (need to add better vent out back but keeping the overall feel and design). And with the powerplugs coming out of 2 places (2 Hd&2floppy to the front and 4 Hd and motherboard to the side). Toying with the idea of allowing space underneath the PSU for the ribboncables for the floppydrive (IDE ribboncable usually goes nicely over the top of the original PSU and thus not blocking the circulasion). It should be in the 300W range and with 2 power passthough to power either 2 monitors in a 2 monitor system or monitor and speakers.
Now make me one and I give you a beer. :-D
