Great speed ... but

The speed of the PC is unquestionable.
He came with me to quickly (2 days delivery)
Now for the but:
No power cord!
PSU was loose (what's so hard about, continue to attract screws a quarter turn?)
A small screw was funny walk (still not figured out where it belongs) in the housing.
The hard drive makes it hard crash (bad feeling to have installed on Win7)

After all, you get what you ordered (down to the power cord).

What do people who do not dare to Tower screwed to look if everything is in place?

What makes the small screw?
Jumps it sometime on motherboard and paralyzes the system?
Heard it for artistic whole system?
Can you remove it?
Questions, questions
In this sense ... in need of improvement

Addendum: Compi been running for two months.
He does without complaint what he intended. The stray screw I have been given a new home in a coil box.
The front USB ports are recessed wrong and too deep.
That the compiler without an operating system or WORD is supplied, is obvious from the description (of course you have to buy extra)
TIP: OpenOffice can virtually everything WORD, EXEL, and Office can also.
Am satisfied, even if the hard disk still is quite noisy.
Ordered graphics card Geforce Ti550 is of course the hammer. 8MB RAM are nothing to sneeze at.
All in all: good computer
