Since SSD's have no moving parts, you can probably mount it with duct tape if you had to! Not that I would, but you won't have to worry about it vibrating loose so much.
You could also check amazon.co.uk for some stuff. I don't buy anything online without checking at amazon first. You never know what you're going to find (like my New Logitech G940 setup for US$199 with free shipping). It was only that price for a couple days, but I snatched it up.
I got my dad a laser printer (brother HL-2140) awhile back for $50 with free shipping from newegg.com.. just happened to 'stumble upon it'. It's only black and white, but so what? His ink cartridges kept drying up from lack of use, and the few times he DID need to print something involved going to a store and buying a new ink cartridge for $20-30. It's worked great for him for over a year now. I just recently ran into the same exact printer at newegg but this time it was $58 with free shipping, but I snatched it up for myself! We also used one of these at work, printing about 400 pages a day and it has held up for several months now with no issues. Great printer, and retails at about $140.
The moral of the story? Make sure you shop around. Your options may be limited in Denmark, but you'll find huge price differences from one site to another. Also make sure you check out the 'free shipping' options. Newegg for example might have a DVD burner for $25, but with $15 shipping, making its total price $40, however you might find a better one for $35 with free shipping, so it's like getting a much better part for $5 less! You just have to pay attention, is all.
Oh and someone mentioned about twin Fermi's being beneficial for FSX... yes you've got a good point there, but Snefens didn't mention it so I assumed (possibly incorrectly) that the new system would be used for the most part, for Aces High in which case a single Fermi is overkill, let alone two of them.
