If you're looking for help with your custom built PC, this is the place to go. I'm a moderately experienced PC builder, but occasionally I run into problem's I haven't seen and after hours of digging through forums without luck I gave these guys a call. I told them my problem over the phone and they were able to help me diagnose my RAM issue almost immediately, and offered to help me test it if I brought my computer in, which they did for free. These guys are knowledgeable and forthcoming with advice on how to address issues you might have with your custom build. I look forward to working with them in the future. They also have a lot of experience working on Macs, so if you have one that's out of warranty take it to these guys rather than the apple store, you will have a great experience.
