Thanks....I designed the chassis around the heatsinks of which I got 5 for 40 off e-bay. The panels I had made up to my design by scheaffer AG, you download the software, design the panel and they post it to ya in a week or two. The panels cost 90 total including delivery from germany! The amp itself is a kit from white noise audio which sounds great to my ears. As a first build I thought a kit would be a prudent way to learn without ending up with a pile of junk.

Yeh psu is elsewhere in a crappy plastic box. The 90 was for all four panels in 3mm thick ally with drilling and lettering. For just a front and rear panel it wouldve been 35-40 and this includes VAT etc...I thought it was a reasoable fee as I dont have access to the tools required and I used a load of letters in different sizes (you pay each time a tool is changed) so you could get the price down.

Looks clean and nice. Where did you get the board's ?

You'r wiring inside could be cleaned up and maybe a heavy guage too

Yep, that is one suggestion I would make - consider fitting some local PSU resivoir caps and using heavier guage wiring for the PSU cabling.
