Actually, I think it looks excellent with the caveat that the shadowing in your first linked picture really adds quality and professionalism. You want simplicity, particularly for tech work where simplicity of design is desired, the font works really well with the caps, and the shadowing shows more thought and quality behind the simplicity. The fact that the shadowing is silver is a nice touch, as it subtly refers to technology and makes me feel slightly nostalgic for the 90s grey machines and the insides of pc components. It does also look excellent on white but you lose the shadowing in the above examples, which are less striking by comparison.
Customers don't want fuss, they want something clear, professional, relevant to the IT industry and not an obvious copy-paste bodge job. Your logo fulfils those requirements.
