- J11/J13: replace edge fan connectors (PCB too thick, cannot find mating for that) with surface-mount connectors, possible replacements from [molex catalogue](https://docs.rs-online.com/8797/0900766b815e6458.pdf), e.g. PCB side: [this one](https://www.molex.com/molex/products/part-detail/pcb_headers/0444281001), could be also [this](https://www.molex.com/molex/products/part-detail/pcb_receptacles/0447641001); fan side: [this one](https://www.molex.com/molex/products/part-detail/crimp_housings/0441331008), or [this](https://www.molex.com/molex/products/part-detail/crimp_housings/0443001000)

- J8: "M.2 PCIe" -> if we decide to keep M.2 over SATA, replace "PCIe" with "SATA"

- J4: the USB3.1 connector needs to extend beyond PCB by min 0.5cm, probably need to find a new connector. Currently the connector is hidden behind the front panel and cannot be used (see [pic](uploads/c73206129d939b1d6c57bf52fc9594ca/20230530_112941.jpg) )

- J12: Move PSU-present/alarm connector closer to the front
|
|
|
- J10: consider using angled connector (with the cables, it barely fits in the enclosure, some danger to strain the cables.

- SMA connectors P6, P4, P5, P2, P3 - I'd make the order of the I/Os different (similar to what we have in the current WRS and divided into INs and OUTs), i.e., from left: PPS_OUT, 10MHz_OUT, AUX_ABSCAL, 10MHz_IN, PPS_IN
