I'm not sure yet. I'm more or less getting all the sellers spare parts, which includes the old original LNB's plus a never one which sits in a modified holder. I don't know which is best as I have never had a PF before. Exciting times to come
You're getting this:
(I almost bought it nyself over the weekend, but it's just too far away from me to be worth it. I have too many large dishes already...).
Its a Cosmos 180cm PF (Swedish mfg from late 80's) with polar mount.

PM looks ok, you need a 36" actuator on that to move it properly / withstand next storm.
If you do motorise the dish, you will need a V-box and separate power cabling to the dish.
For LNB you will need a modern Ku one to mate with the feed-horn provided with the dish.
A better start is probably to try this first:
Konv. UNI GI-209P Flange 0,2dB
Much easier and cheaper than fiddling with matching feed-horns etc.
From the previous owner's pictures, it looks like it's possible to fit a 40mm LNB in the clamp provided.
It is also clear that you should throw away the 40mm LNB that comes with the dish, its feed-horn does not match the dish.
For cabling, do not worry about 40-50 meters. Unless you cross buried power-lines or simliar with your cable, you can start worrying when you go beyond 100m.
As long as you have double or triple shielded, you will be fine.
It is not the signal strength that matters, it is and will be the C/N ratio (støj/signalforhold) that will make reception possible or not.
So, be sure to match the LNB to the dish (get a GI209 or use the provided feedhorn with a C120 flange LNB, possibly using adaptators).
Then have a single (or double) length of good shielded cable.
Don't skimp on F-connectors, do get compression types if you can - they're much better at being RF-irradiation tight.
With the 180, you will have difficulty getting 2E/F/G on the same orientation.
Even on 120cm dishes near Copenhagen, there's a clear discrimination if you point to either 2E or 2G (extremes).
Ideally, you will need the motorisation.
Compromise is probably to align with 2G (HD channels), then live with the SD performance.
Looking very much forward to progress reports!
