Default FS: O2 Headphone Amp Assembled Boards

Hey, I just finished putting together my O2 amp and it sounds great. I'm going to assemble 8 more, so I'd like to sell this one now and 7 more when they're completed in a week or so.
This will help me raise money for a headphone upgrade

I've got the board, batteries and power supply, shipped in the US for $120. Overseas for $120 + shipping. All you have to do is figure out a case.

I'm new to the diyaudio forums but I've sold a lot of stuff on hardforums.com as user id "hoffstetter".

Here's some pics, let me know what you think.

UPDATE! I have been working on a good way to sell these with a case but the expensive metal front panel was the only thing stopping me. Well I found a solution.

This is my new laser cut, clear acrylic front panel! The lettering is laser etched on the back so the front is smooth. The one pictured below is 3mm but the rest, the ones I'll be selling, will be 2mm thick so there won't be any risk of obstructing the ports. I hope the pictures convey how beautiful these are in person.

So now I'm selling these with amp, case, front panel, batteries and supply, for $135. I'm using the black aluminum case that RocketScientist recommended. I won't have the cases until Tuesday, so they won't ship until Wednesday.

I got the rest of my front panels in today! Don't worry the burnt look is just on the protective plastic covering.

I also got the cases in so here are some pics of the assembled amps. I just need to get the boards grounded to the cases and they'll be ready to ship.

I completed 7 amps on wednesday night. 3 of them are sold and paid for already, 2 of which shipped on thursday. One more is pending payment. And I have two locals inquiring. If you want one, please speak up quickly.

aerohoff, please resize your images before uploading. 2048 X 1536 is too big! 1024 x 768 or 800 X 600 would be preferable.

Not all members have fast internet connections, and some pay per the megabyte.
