Last week I have completed the changes in the case, learned fine differences between what is in ATX standard and what is allowed in 1u cases, and what weird kinds of thumbscrews exist in the world. So today I have requested the new prototype with changes and thumbscrews, and returned to work on PC boards and wiring. My father is still working on the cooling system (filling machine is done, soldering rig almost works), and it looks like they can go into production soon.

Doesn't sound exciting, does it?

thumbscrews! a 1U case with thumbscrews! i'd kill for one ;-)

typical rackmounted 1U case has from 5 to 10 screws, flush with top cover, which have to be removed before you can reach anything but hot-swap SCA drive connectors. My favourite is when same screws are used to hold both cover and rails - so you cannot even hang your box out front and work in the rack, with power/ethernet connected - you have to take it out, open, do something, close, put it back and pray...

another suggestion: some kind of support for long PCI cards besides riser connection. In all 1U/2U cases i have seen, full-sized boards tend to wiggle when installed.

p.s.
i have spent last couple of weeks fighting with very expensive Sun hardware RAID array (fiber-attached to SAN). One really appreciates quality firmware when things costing over 20K run out of coredump space after yet another assertion failure...

Two thumbscrews open the front compartment (hard drives, fans), two thumbscrews open the back compartment (motherboard and everything on it, heat exchangers).

Hard drives are on brackets held on screws to the floor of the case, motherboard standoffs are all on screws (can be moved around to accommodate anything ATX).

When both front and back covers are removed, one can unscrew five regular screws to remove the power/cooling assembly and Ethernet jacks on a bracket. What will be left in the case will be is just wiring, and the LCD panel.

PCI brackets will be held by the top (what is actually "right" in the case), and I didn't think about any additional support for the card's edge opposite to the bracket, however there is enough space to add some bracket that will support it. I can add two screws to hold such a bracket if someone will need it.
