I love the IIgs. I still have the original my family purchased back when I were just a wee lad. Sadly, my son blew out the VGC by hot swapping disk drives. I was able to get a ROM3 mainboard for cheap off ebay a few years ago and drop it in as a fix, but I'm still looking for a replacement VGC to repair my original board. But the ROM3 is nice. My current setup has an Uthernet II, TransWarpGS running at 14MHz, the CFFA3000, a VidHD, DarkSound Stero card, and a 4MB RAM card by Briel. I also put a replacement power supply by ReactiveMicro to keep everything running. It's such a fun machine to jump on. Man, the deals with the devil I would have made to have these upgrades as a kid... .
I'm curious about those fans, I have one on the power supply cage, which brings hot air from the slots area and up through the top of the IIgs case, but I keep the lid on.
@krishnadraws - I saw this post a while ago and had meant to come back and comment... I'm also a IIgs user. I never had one growing up (from a IIe to a Mac) but bought one a number of year ago and didn't really do much with it. A couple of years ago I set it up and started playing with it and I have to say I was blown away at just how cool it is. I've now got two IIgs systems but only one is in regular use. They are both ROM 01 systems (one was upgraded from a ROM 00) with 4MB RAM cards. My main system has an Uthernet II and a MicroDriveTurbo and the second system has a Booti card. I run my video through a Scart to HDMI converter. Both systems are running 6.0.4. I really would like a Transwarp GS and am debating between waiting for the 2.0 version from ReactiveMicro, or just jumping on the current version 1.1. My main unit has a ReactiveMicro power supply and my backup unit has a recapped power supply (and logic board).
There is a program called AFPBridge that will allow you to mount AppleTalk shares over TCP/IP. It can be used to connect to AppleTalk servers over the Internet, or locally. I have a Debian VM on one of my machines that runs a netatalk server which both my Macs and my IIgs connect to. There is also a need program called Treehugger that, along with Harmonie allows you to print to TCP/IP printers that support HP's PCL (most networked laser printers do) so you can print from your IIgs over Uthernet to modern printers. There is a pretty active IIgs community on Captain's Quarter's BBS (cqbbs.ddns.net:6502).
I did laugh about the Hard Drives International PowerDrive though- The first hard disk I bought (80MB PowerDrive) died just after the one year warranty and I learned that Hard Drives International had given me a refurbished mechanism. They wouldn't do anything for me to make it right so to this day whenever I see a PowerDrive I see a bit of rage.
