I would recommend single store. Most of the online stores (excluding prime abgb as far as I recall) have a 3day testing period for DOA returns (prime has 7 days). If your shipment from either of the 2 stores is delayed, you get less build and test time within the return window.Also, is it fine ordering the parts from PCStudio and MDComputers separately or should I buy from a single store?
