One thing to note, da-x doesn't sell systems which are ECC RAM based, Xi-machines does.

da-x is very strict. They don't sell you a PC if you want something which conflicts with their agenda.
It was at the time when Win8 was out and in the last moment, when the Laptop was ready designed with
their technical support, the CEO of company stopped the sale, because he didn't approve Win7, although they
sold Win7 based for many many years and told me weired stories how good Win8, but bad Win7 shall be.
But I don't like several things around Win8 and have simply different requirements.
In that regards they are very inflexible in terms of customers demands.

That was very disappointing. Especially as I told from ground up, that this is simply an office and casual gaming
Laptop for my wide, not for recording and that I want Win7.

I only intended to buy from them, because they offer to sell customized Laptops, where you can influence what components you would like to have. All I wanted was a good quality Laptop with components that make more sense for her, as I didn't find anything useful from other vendors like Lenovo, HP, etc.
