Motherboard, while seemingly good data throughput, seems cheap as they can get away with.
Since I can build my own, and have on several occasions, I'd spend the money and ensure the parts weren't factory rejects or made so proprietary that they couldn't replace them.
I notice TH mentioned replace-ability of parts, yet I didn't see anything where they tried part swaps. Either I missed it, or we could have an unsubstantiated claim on our hands. HP has managed to produce some decent stuff under the Omen moniker though. (I have their HSA-D002K Omen keyboard w/mechanical blues, It's excellent for the price I paid and beats any of their cheap stuff they package with their systems.)
