I'm not a big fan of the 1u strips, it just allows certain manufacturers to create their own format modules to corner the market. If it was an Intellijel 6u then i would be more interested. I think 1u tiles are ok for the micro lunchbox cases - that makes sense, but for the bigger cases - no, not for me.
The first thing i look for (after hp) is for a reputable power supply, closely followed by the weight. Also, whether it can it be patched up when closed and also whether i can get it on a plane without putting it in the hold.
I have monorocket 2 x 6u and 1 x 12u cases - with both makenoise and internal monorocket power. Well built cases, but waay too heavy, especially the 12u with internal power. I also moddied the lids of the 6u with new rails and tip top power as i realised i wouldn't be hand carrying them again. Monorocket power is also questionable.
I have an isms system also, which is surprisingly heavy for the 3u size. With the Pelicon case (7 kg) you are pushing 12kg, but at least you can check it in with confidence. The case is built like a tank and has rollers on the bottom.
My next case will be an Elite 416 portable 12u - primarily because of the weight and extra hp to replace the monorocket 12u.
