I have checked the specs...
The cpu is beast, but it has integrated gpu, and I am not sure if I am comfortable with that. Besides, does that system come with preinstalled win7 64bit?
Yeah I don't have much first hand experience with integrated graphics so I can't really give you much information on that. If I was buying I would probably get one with a video card because that's what I've always done. As for the systems coming with windows... I don't believe they do, they don't mention anything about windows coming pre-installed so I'm guessing they don't, still I don't think that should make you shy away from building your own.

AMD FX-6300 Vishera 3.5GHz (4.1GHz Turbo) (6 core) Socket AM3+ 95W Desktop Processor
GIGABYTE GV-R726XOC-1GD Radeon R7 260X 1GB 128-bit GDDR5 PCI Express 3.0 HDCP Ready Video Card (Model:GV-R726XOC-1GD)
1 tb hard drive
8gb ddr3 1600 memory
Decent looking case, and a nice Mobo to boot.
Would last you for years... It's a good video card but if you ever need more that's a simple upgrade.. and you can just buy 2 more sticks of the same ram for 16gb memory.
I'm going to be buying something like this within the next few months, my current system is on its last limb and I'm still using windows vista
I would check the shipping costs to europe, you can add the kit to cart on newegg and then type in your zip code to estimate shipping costs. Windows OS new will run you about 100-140$ I think.
