バード電子さんからHHKBオプション品としてキーボードブリッジが発売されていますが、CF-SZ5には適合しないので、自分で作ってみました。
KBBridge-LN_CF-SZ5.zipをEmerge+さんのレーザー加工サービスでカットして貰ってください。 (A3サイズなので、2つ分入ってます。)
滑り止めのゴム足はクリアで小さいのを探したところ、和気産業さんのソフトクッション CN-020が入手性も含め良い感じでした。

カーネル3.4系と4系が選べる。ドキュメントによると3.4系はGPU含めフル機能使えるが発熱問題があるらしい。4系はGPU等一部使えない機能があるけど発熱が抑えられるとのこと。
