“An excellent service and customer care, right from the beginning and afterwards!”

“Although I don’t think I’m but what I do seem to be categorised as is a power user. But I didn’t want to go for the high-end components for everything. Andy helped me right from the start to guide me to find what I’d need for what I do. I’m very happy. I installed my Japanese Windows 7, so I had to install various drivers myself to check the system but then when I had a few questions, Andy immediately provided all the information I needed to make sure my PC works perfectly. Thank you again for all your help and now my creative works are going faster than ever!”
