Ive never used them before although Ive heard of good reviews. This was the 5th company I rang today to ask for a PSU / Powerpack who actually knew what one was! Theres an awful lot of dumb people out there with shops and these seem so far to be firmiliar with pc termonology and technology. I should write a book with some of the stuff I got today from other places; Q: Do you have a copy of windows Server 2003? A: Yes, we have Microsoft Windows Office. Q:No Windows server OS 2003. A: Whats that? Q: Im after a PSU 350 with ATX connections do you have one? A: Err. The boss isnt in right now but we do all softs of software. Q:Im after a PSU 350 with ATX connections do you have one? A: For what model computer? Q:WHAT? Custom build?? What you on about for what model? A: Oh, ok Ill ring you back with the price. They never rang back!!!
