|"there is an intel chip that reads SB82437VX and is dated '95"|
That's the Triton II chipset. It will take 128MB of RAM, but it can only cache 64MB of it. This means that if IBM installed an L2 cache, any memory that you install above the first 64MB will not be cached, which can really hurt system throughput. So if you find cheap SDRAM on ebay, don't buy more than 64MB of it. Fortunately, it doesn't take much to satisfy Win95. '95 smokes on a DX2-66 with 32MB; it'll burn the house down on a Pentium with 64MB.
"Would I be able to add a second hard drive, a Caviar 21000 AT? That is compatible with this machine correct?"
Yes, that drive will work with your machine.
"Do you think a Soundblaster Pro 2 (8 bit) would be a good card to get?"
8-bits indicate a monaural card. Go for the stereo Sound Blaster 16.
An old ATI Rage PCI video card will run your DOS games quite well. The Rage also had great 2D acceleration, which will give Win95 a little more pep than the EDO-based onboard chip does.
Do you know of any small PC shops in your area? Many of these smaller guys hold a ton of old hardware that they sell for a couple of bucks each or even give away. That would be much easier and cheaper than eBay.
