price times 230% too high

Seriously, you add a sink that just costs 3 or 4 copper, with a card that is in open price 30 (probably less for a company, since the VAT intervenes only trailing) making 34 , using the VAT 20% was 40.80. At 70, you get a nice 29.20 so profit, to route reinjected into your stock (sorry, but it costs in the 10 to process such a product, not 20!), And we resell it. This is not a little abused there?

Overrode the price (which is a strong argument for equal products), it is a good idea to offer something dissipate heat, as the most powerful processor is required to turn on more demanding applications (I think including Ubuntu, and even an Asterisk PBX server (asterix?) for a small company of 50 people (very useful to have an internal phone!), or even install several different services, distributing the load by communicating the different servers and therefore the different services.
