Trickiest bit with the heatsinks was tapping the M3 holes in the top and bottom - I ended up buying a pillar drill to do the job, was fairly straight forward after that.

Chassis top and bottom covers were laser cut by lasermaster.co.uk, not as expensive as you might think; the front panel and volume control were cnc'd, they were a lot more expensive but I managed to get a decent price from starrapid.com, brilliant quality.

Thanks, that would probably be better; I'll carry on looking for something suitable. Think I might buy these ones anyway and see how much strain they gan take.

Not seen Lasermaster before, thanks for that.

A pillar drill is money well spent, an essential item for everything other than stamp collecting.

I wholeheartedly agree. I use my pillar drill (aka drill press on this side of the pond) all the time.
