Other Mods

Just modded my early fat PS2 with a Notua fan and the OEM Network Adapter SATA conversion. I have a MemCard Pro PS2 with OPL etc on it and a 2TB SSD. I have it ran into a RetroTINK 5x with HD Retrovision cables. Also swapped out the CMOS battery while I had it opened up. Are there any other meaningful mods I should consider? I wasn’t really planning to mod it now but receiving the MemCard Pro and the Prime Days deals on SSDs made me go ahead and jump in without doing as much research as I usually do.
