As everyone knows Colchester is worlds leading location for computer supply (outside silicon valley and China) which is handy as I live nearby and could pickup the PC on the way to work (so I don't know about UKGS shipping skills) the gentlemen who served me was very polite and efficient.
The UKGC web site is simple and easy to use and seems to be available 24x7 which is handy as their store wasn't open when I raised the order (2am Sunday morning).
Being from East Anglia I wasn't in any sort of hurry to get PC I was expecting a couple of weeks it took 1 week which was fine; it gave me time to comes to rems with the prospect of becoming the owner of such an advanced piece of technology.
At work I run clusters of 100's of servers and I know they fail particularly early in their life so I was happy UKGC assembled the machine and put it on soak test before releasing it to me.
UKGC have a good job management system and their staff clearly use so I got progress email notifying me order processed, parts received, build complete test started, delivery requested.
I got the PC out of the box and it booted up fine.
It is blisteringly fast, although technically that is little to do with UKGC and more linked to Intel, Corsair & NVIDIAs mastery of silicon design and fabrication.
