Disclaimer: I see your all caps above re no water, then you did say “any more [XP is] welcome”
FYI: If you decide to build it yourself and you change your mind about liquid cooling, I had excellent results on TR with this CPU cooler: Silverstone XE360-TR5 cooler for AMD socket sTR5/SP6

I mention because the pump is located in the radiator (which you could mount externally) so the profile on the CPU is extremely small.
Note: I have had a liquid cooler pump leak and fry a mobo, but this config may lower the risk.
