After collecting parts piecemeal for probably almost a year, finally put together a case today — with a lot of help from a friend who is far more handy than I (my main contribution was slicing open my thumb while trying to shorten a screw).
Very close to what @Tan_Sat posted above, but with an extra 1u row as well. Used @Dewb’s drill template, so thanks for that!
Will post parts list below pics, in case that helps anyone.
Didn’t want to wait for the LZX power module, so just built this 1u Synthrotek power inlet kit:
Added feet, so the screws on the bottom don’t scratch tables:
Ended up using the same exact feet for the spacers on either side of the rack bracket since they were a perfect fit:
Harbor Freight Apache 4800 XL Case $55
Malekko Power $229
Cincon TRH100A120 DC Power Brick $45
Synthrotek 1u Power Panel $18
Vector TS169 Rails x 6 $66
Pulp Logic 1u + 3u + 3u Case Bracket $40
M2.5 Square Nuts $12
& ~$10 misc. hardware
= $475
(not including taxes and shipping, but I also picked up several of those things on sale or used, so I estimate my total cost was more like $450)
