Havent seen a decent one. Most servers are bloated with ugly customs, poorly coded or have low playercount.
rare to find a good 2011 feb revision type server that looks clean RSPS List | RuneScape Private Servers - RuneLocus iterate through the list maybe u find something =)
We meet all your requirements for the server, however, the only thing custom is the Wilderness and our home area. However, you'll see that this is for QOL and will not ruin the OSRS experience you want.
