I have been thinking that it's fair to consider a 40-50% resale value on all mining hardware purchased, more in cases of super high end things like 6990s.
Some pool-mates and I were talking today about the idea of colocating mining equipment. Considering things like electricity and cooling, it's a great idea.
But who is going to buy your Sempron 140, your pci-e extenders, your 2x650w psu or 1x1200w psu, your outdated motherboard and your 2gb low speed value ram?
My contacts come into play, i can be certain for anything that can be used in mainstream i will get at least something.
Then comes the local forums, auctions etc. which will take the 650W PSUs, 1200W PSUs etc. for better prices.
Even 5+ yo mobos have market here, so does even original DDR or even earlier! Infact, very old RAM is the most expensive around here (10+yo), and there is still people needing those oO;
and in most cases, just upgrade CPU + RAM and you got a highend machine
All you listed, except PCI-E extenders are easy sales. PCI-E extenders are a minority cost (under 5$ each) and does not matter even if i end up throwing them out. If i get x16 PCI-E extenders, those should rather easy sale to gamers with cooling issues.
The low end vid cards will sell as well, no probs.
One thing about Finland: People are poor. REAAALLY poor. 40€ might be an painful investment for some. And i'm serious! Many people working full time earn barely enough to feed themselves, even if not at minimum wage because you loose the social benefits and acquire extra costs to be able to goto work. Some for being already broke and paying off debt can barely afford anything. Even at mean wage you can't afford much, 200€ will be painful for many middle wage people.
Also stuff costs insanely much here, you are lucky to make a daily budget for food for single person below 3€ a day, and if you want to eat proper foods and properly, without skimming it's easily 8€ a day. Pizza costs regularly 8-10€ and Big Mac lunch is 7.5-8€. 1.5L bottle of coca cola costs 2.5-3.5€ (cheapest knockoffs are 1.3-1.5€/bottle). Small cup of coffee at a gas station 2€. Pint of beer at cheap bar is 2-3€, regular place 3-5€, expensive 5-9€. 1Liter of milk is about 1.5€, 400gr (0.4kg) of macaroni is atleast cheap at 0.28€. Cheese at least 6€ per Kg. Tuna costs about 1.2€ for 150gr (0.15kg) or cheapo with fishbones and stuff 0.5€ for 150gr. Coffee packet of 400gr is about 4.5€ for good brand, cheapo about 2.9€.
I just bought Antec 300 case yesterday, cheapest place asked 58€ for it, inc. VAT 23%. I just had read on one forum someone bought the same case new at US for 40$(28.37€). USB Sticks cost atleast 6€ each. DDR3 RAM costs close 10€ per Gig (vs. at US you can get 2x4G for 65$). It makes very often sense to order from US/Hong Kong/China even with insane shipping fees and customs duties, esp. for small stuff like cables. DVI-I to VGA adapters cost 8€ each here! (vs. order from HK 0.99$ inc. shipping). Even on enthusiast forums it's kind of rare to see high end computer hardware being sold oO; Highend is REALLY hard to sell here, when 8800Ultras were not that old, next gen was just released, people were bitching my asking of 300€ per card (at the time they were listed at around 650€ per card new). I tried to sell a Quad Core Extreme CPU, 2nd fastest, listed at the time at 950€, people were bitching why i won't sell it for 200€ because a 60€ core2duo is so much more worth for money.
So the low end stuff has their market, and it's a huge market. I get constantly question "can you get me a HDD for even 5€ cheaper??", "Can you get me a brand new computer, i got 100€ to spend?". Most Finns are trying to nickel & dime everything they can.
Median US income (2007) is about the same in euros as mean FI income (2009 or 2010), but taxes are through the roof. At US i hear a gallon (3.97L) of fuel costs about 2.50$ (~1.79€), so you get almost 4 times as much for just a bit higher price. My belief are rents are about the same in USD than here in EUR, so ~39% difference. etc etc etc. the list just goes on.
Because everything costs so damn much here, when people go abroad a major portion of the trip is shopping for regular items (not souvenirs or novelties), because even expensive stuff abroad is dead cheap for FI prices! Before Estonia had to raise prices due to EU, there was a lot of people constantly taking trips there to bring alcohol and tobacco, as they could get 100% profit margin, and it would still be like 1/3rd of the price here! :O
