Partpicker has it's share of problems
another that comes up often is things like not flagging high data rate DRAM as being problematic with low end locked CPUs i.e. saw one rig laid out with a 4460, an H97 mobo and 2800 DRAM, while yes, technically you can prob run the DRAM with that combo best would be at 1600, and who wants to pay a huge premium for 2800 DRAM if it can only run 1600. Have also seen it show Hyper X Fury DRAM as compatible with 775 mobos, which A) 775 doesn't support PnP which is what the Fury run off of, and B) Fury is made with high density memory ICs (chips) which aren't compatible with the the chipsets on the 775 mobos
