These all aluminum, heavy-duty cases are designed and built to house “open air” PC rigs, such as those used for F@H, S@H, BOINC, LN2-cooling and testing/benching.
The trays come in three sizes: ATX, EATX, and 4p/MEB/SWTX.
All of the trays can be stacked with the purchase of two additional posts (all necessary fasteners are included).
ATX Open-frame Tray
The open frame ATX size tray measures 8.75 x 17.75 x 10.75-inches (H x W x D).
ATX-size tech tray
With the addition of an optional lower tier, the tray becomes a full-blown tech/test station/bench:
Drives are mounted to the rails via rubber grommets that are attached to the drives with button head bolts (M3 for SSD/OD and #6-23 for 3.5-inch hard drive):
In response to the video review by LinusTechTips, the tech station has been improved with added support beams for the PSU and a radiator.
