im having two levels psu on one and lasers and optics on another so it should be fine.
LOL yes i know you will understand once its done, ill post some picsLOL
The whole point to heatsinking is as much surface area as possible, not as much aluminum as possible.... Just buy a small heatsink.. simple

this is what i mean.
so both psu are mounted to the base plate and then the side that gets hot is mounted to the aluminium bar

Andy, the aluminum bar is not really the best thing to do. It will soak up the heat from the power supply but because of it's large volume to surface ratio it won't be able to get rid of the heat and then you'll just end up with a hot power supply and a hot bar. It's better than nothing but you'd be as well off by just attaching a piece of sheetmetal to the power supply.
will holes help??
there is going to be a fan blowing over/onto the alum bar

As Dave said its surface area thats important. Thats why CPU heatsinks have fins rather than being a solid lump of ally. A 3-5mm ally plate in an L shape bolted to the base would be better as it will draw heat away from the PSU and into the base and/or some heatsink fins bolted to the L shape will assist greatly in dumping the heat. Its effecient heat coupling and subsequent transfer to moving air that you need to acheive.
Take a look at what I did - very simple - my baseplate was getting too hot so I cut some fins off some CPU heatsinks (its one heatsink cut in half) and I screwed them to my base plate with some heatsink compound in between. They are right in the airflow of the fan you see and have made a wapping improvement to my cooling - its now not a worry about heat in the base plate - and its pretty crude.
