BTW I'll be on my 3rd case from that 8audio, they are good quality for the cost but adequate ventilation for class A stuff could be an issue with them.
For sheetmetal/steel lids I've a 1/2" punch to try to make neat sets of holes with, but for the thick solid aluminum lids on these I do plunge cuts from below using an aluminum cutting circ saw blade:

 
Will probably black-out the slots above & wet-sand the coarse finish faceplate above.   As we know casework is a large part of a DIY job & I'm finding attractive/adequate ventilation the more difficult part of that...  Of course when a case does not already have it or when not using machining services.

That is one nice looking case. Not sure if the ventilation is enough though.

I have also used their case and it is tough to drill large holes into aluminum without the proper drill bits. I had to drill a 2.5 cm diameter hole using a 1 cm drill bit took me 30 minutes and lot of sweat to get good results still it was not flawless though the neutrix headphone out covers it. If it is to be done for the top plate it should be perfectly round. Use a circular drill bit set used to cut holes in doors to fix locks etc. 
 
Also buy the rhodium plated tube protectors from 8 audio, will look cool.

@ cfcubed. You recognized it right it is the same casing had been searching an year to get a case which fits my EHHA perfectly.

I am upgrading my heatsinks and when the air inside heats up the top panel gets a little warm in an air conditioned room even after long listening sessions. If I have any heating issues will try to make something like a laptop cooler cum isolation stand for the same.

Just finished a somewhat maxed out PIMETA v2 today.  Some tweaks include the NiMH battery charger using a 9.6V NiMH battery, brown dog adapter for separate L/R opamps, all Vishay/Dale resistors, R11 resistors, Class A biasing, 3 power reservoir caps, C6 L/R direct soldered to R6 L/R, Alps RK27 potentiometer, the list goes on and on...
 
Here are the pics!

I don't know how people can carry bricks like that around. And I thought my Zune + GSP/E11/Cmoy....was big.....



I don't wa't around and listen to it.  I throw it in my bag for when I'm working at a desk or something in the Engineering building or main Library.  Its more a desktop away from home type use -- I don't really listen to music while walking around and such.

You mean you don't have a theme song you walk the halls and streets to!? haha    that would be a good thread idea, "Song you like to play while walking amongst many people, aka theme song"
 
I didn't think it was that huge, it would definitely fit in a coat pocket.

My Super Simple 6DJ8 amp:
 
Elna Silmic II electrolytic capacitors
Solen Fast Cap output capacitors
Alps 'Blue Velvet' pot
JAN / Phillpis 6922 tube
 
This makes for a dynamic and airy sound, liking it.
 

 

 

 

 
Nothing special on the casing. A crude Eddystone / Hammond case painted in black, about as simple as the amp circuitry. Sweet and mellow.
