I would suggest that future designs at the least feature longer anchoring screws of a larger diameter.
Anchoring the heatsinks to both panels would be even better physically, and for heat dissipation, but would make opening the unit more difficult.
Someone else mentioned copper heatsinks. This would be a nice touch also, so long as there are no galvanic corrosion issues with a bi-metal design.

This is an open-source project, the sources will be released when the product ships.
Does that include the PCB design files? What else? Is there the possibility to buy just the blank PCBs from you, and gather the rest of the components and assemble them ourselves?

I'd return them for a refund.
I think the ~$300 7950s are more appealing to miners. I hear they outperform 7970s at Scrypt.

I have some already-built-and-mining rigs doing LTC, that I'd consider selling whole if the price was right.
Right now I have a quad 7950 rig running in an "open frame" with powered riser cables that makes around 2.275MH/s at the factory clocks.
I'd let it go for BTC20, shipping included within ConUS. Maybe that's a high price, but I don't really wanna sell it.

I have some Sapphire 5830s mining LTC right now that I'm planning to phase out. As many as 4 of them. They're clean and still under warranty (one is a fresh RMA), though I don't know if the warranty will transfer. If manufacturer warranty service is needed after the sale, I will try to offer what support I can to make it happen.
They run very cool and quiet. I have the original retail boxes too in good shape if you want them.
I don't know what the market is like for these now. Looks like eBay is pretty well cleaned out. How does BTC1.25 each sound? I'll accept escrow.
Where are you located? I'm in the US.

I'm hoping my EMS shipments go better. I declared them as RMA/Returned Merchandise.
For anyone not wanting to deal with the trade-in, if you'd rather just sell your Icarus or Lancelot, I would gladly buy it from you at a premium price, and use it myself for trade-in. PM me if you're interested.

I don't know precisely where fault lies, but BTC-e (or its users) potentially face a very real loss over this. There were users on the other side of those trades expecting to receive TRC for their purchases. TRC which BTC-e accepted for deposit, but now no longer has in their wallets due to it being "forked away".
Because the TRC were forked away, BTC-E should reverse the trades. Those who bought the TRC don't have valid TRC...the forked away TRC cannot be transfered out of the exchange. If BTC-e still has those TRC in the system then they are letting people trade invalid coins and there is an inbalance in system. I do believe that is the situation. If BTC-e were to reverse the trades, I would owe them BTC instead of TRC. I would prefer to owe them the BTC, actually, since I sold the TRC around 0.00225. To buy it back now would cost about double the BTC. I "fought" to have my fork win, but I gave up after it fell 200 blocks behind.
Even if you went 200 blocks ahead, you would be banned by all new nodes the moment you would attempt to publish your blocks to legit chain. Why? What would have made the nodes reject my chain? These patches do nothing, as soon as difficulty drops a miner with a lot of GH/s exploits this difficulty bug to mine at low diff, then when the difficulty increases by a factor of 3, he stops and waits.
I believe the past 2 TRC updates have made efforts to "fix" the oscillating difficulty, and that 0.1.3.36 and/or .38 make further attempts towards that. Note that previous sha256-based altchains have only been able to solve this problem by implementing merged-mining with the BTC blockchain.

All you're gonna get for $2.5k ASIC-wise is a share in someone's mining op. Look in the Auctions subforum for shares of CoinHoarder's Avalon Batch 3 op. Mind you, that's not gonna get going until batch 3 ships in May or whenever. Or you can order from BFL and pray with the rest of their customers. Now if you have BTC2.5k, that will indeed buy you an Avalon right now. I'll sell you mine right now for BTC2.5k. PM me.

Don't need an SSD. Any old hard drive is fine. I use a 2GB USB Flash drive myself.
12GB RAM is way too much. 2GB is fine.
I just built a rig around a 970A-DS3, with 7950s. I can't get the 5th card to work (in the slot nearest the CPU). The other 4 work if I leave that one out.

Any particular reason you don't close your BTC-e account and just trade elsewhere? Since they are clearly at fault, I don't see any ethical reason not to walk away from it.
I could do that. I'd lose about 3.2 BTC that's in the account. But I like being able to trade on BTC-e. They have far more volume than vircurex, and far more currencies than mtgox. I could open a new BTC-e account, but they might figure out that it's me and lock that one too and seize its assets. Plus I don't want to piss off the Russians. I knew what was happening at the time, with the fork. I had kinda hoped I could have my fork win (by being longer) and be accepted by 0.1.3.33, validating all those coins and many more still in my wallet, but that didn't happen. I think I'll mine the TRC and pay BTC-e off over time. I don't know precisely where fault lies, but BTC-e (or its users) potentially face a very real loss over this. There were users on the other side of those trades expecting to receive TRC for their purchases. TRC which BTC-e accepted for deposit, but now no longer has in their wallets due to it being "forked away".

There are 240 chips in a regular Avalon, not 230.
3 modules, each made up of 8 submodules, of 10 chips each.

Were you selling mined TRC around late 13 / early 14 April? I missed the 0.1.3.33 upgrade, and at the same time, BTC-e appeared to have missed it too.
I ended up mining on a forked chain, depositing to BTC-e (which they accepted, also being on my fork), and selling for BTC.
Now that they've upgraded, they have locked my account for withdrawls, and say that I now owe them 6921 in "double-spent" TRC.
I "fought" to have my fork win, but I gave up after it fell 200 blocks behind.
It looks like I'm not the only one. I've seen lots of other BTC-e users posting saying that their accounts are also locked for withdrawls. They probably have no clue the fork even occurred.
Now I didn't see this 0.1.3.36 announcement until now. I wonder if BTC-e will see it in time this time...

IMO, pushing out a mandatory update with a 2-3 day window to apply it is asking for this kind of trouble.

Yeah, for production you wouldn't want sockets, but for prototyping, wouldn't having that be handy?
Or would the added wire length destroy the quality of that 282MHz signaling?
