That looks to be a Laing DDC pump (Decent), whats the info on the sticker say?
I can't id the block but it looks pretty groovy, there looks to be a name marked/stamped on it but I can't make it out
Compression fittings, another mark of quality usually
240 radiator and the thing at the top is some sort of reservoir I'd assume but it almost looks built into the case?
no writing on the front of that or is it just a waterlevel view from the front?
Overall I'd say if you are keeping the comp, keep that cooling,
its old water but even old water is still better than stock,
That was topline gaming kit at one time, R.o.g. badge on the chipset hehe so it would have been decent cooling,
hell even if you ditch the mobo and chip, keep that loop as a startpoint into W/c because if you ebay that W/c gear you won't get much,
it will serve you better being used to cool that rig
