This is a project born out of chronic shoulder pain from years of lugging heavy cases to LAN parties. I've tried case wheels and trolleys, but there's still so much lifting out of cars, through doorways, over cable run covers, over rough carparks, etc. I also have CFS, so reducing my exertion at LANs is important in reducing my recovery time. My existing system is a full tower aluminium case with 10 drives, plus an external mid tower steel case with 14 drives on a SAS link. Both cases weigh about 16kg. My goal is to carry nothing over 10kg. My solution is to split the setup down to 4 cases. PC + three 8 drive enclosures. There are SAS drive towers out there that do this, but I could only find them in steel. This gets the weight down to 11kg per case at best, but I want something closer to 8kg so I've opted to scratch build my own from aluminium. Since there's no motherboard in a drive tower, the design is pretty simple - 8 bays, a small PSU, and a SAS bracket to convert internal cables to external ports. Design goals: Lightweight SAS interface Toolless Anti-vibration mountings Front access drive replacement Carry strap that doesn't interfere with panel access Power switch Quiet Cool Compact Minimalist design Things I don't need: Hotswap Cosmetic lights Activity lights, other than a power light Low cost First I checked out Lian-Li aluminium drive modules, but they're based around 5.25" bays which would bulk out the size a lot. So I opted for a full scratchbuild. Bunnings sells a thing called Connect-It, which is 25mm aluminium tubing with plastic corner connectors. I've seen cases built with it but most of them look too bulky for my liking. It's really designed for furniture. So I bought some 12.5mm tubing with the intention of making my own smaller scale version, with 3D printed corner connectors. This didn't work out for a few reasons, and I discovered that using 25mm tubing would only make it a few hundred grams heavier and also a lot stronger. It also has other benefits, since the corner connectors are hollow the tubing can be used as a cable conduit. The design went through a few iterations until I settled on something like this: I actually started on this project 3 years ago and finished the first case in October last year, so I can show you some juicy completion pictures already. I had the first case anodized in red. This is the Red 1 case. My first PC in the 80s used to boot up with a flashing RGB thing that I can't find documented anywhere, but from memory looked something like this: So that's my inspiration for this project's name and colours. This worklog will document the construction of the next two cases, Green 2 and Blue 3. I'll post some photos I did for Red 1 as well, which are a little bit different because I was designing as I was building.
