My experiences with CCL have been far from great. I purchased a 'bundle' from them consisting of a motherboard and preinstalled CPU/cooler and RAM. I also purchased a PSU. The original bundle would not power up and after wasting several hours I diagnosed that the CPU had bent pins (as stated this was preinstalled). Had to send back the whole bundle and was sent a new one, once again all components pre installed. This was more promising and allowed a boot to bios and then an install of the o/s. Then, after a reboot, the system would not POST correctly and the EZ-Diag light for the CPU was lit up. I tried several successful bios flashes (can be done without components installed) without success. I created a ticket on CCL web site and didnt get a response. Waited a couple of days then raised another. Still no response. So I decided to fork out on a new motherboard from another supplier. Installed the CPU and RAM and over 2 weeks later the device has been stable 24/7. From this I dont think it's hard to diagnose that there is an issue with the CCL supplied motherboard. So I rang them and after being passed around the houses had the fault logged. I then got an email stating to send ALL the components back. When I explained what I had done to diagnose and that the device is required because it is a 24/7 CCTV system they refused to budge stating that the warranty was ONLY for the whole bundle. I have tried to explain that you can purchase the items separately, including the motherboard, and I am only wanting them to confirm my diagnosis. They are flatly refusing to budge. I do think in some situations a little common sense and flexibility is required.
