It looks OK, but you might not need a Cele 600 - a 566 might do if you are going to stick with the slow performance of a stock Cele. Even better would be a Pentium III like a Coppermine 550E or 600E, if you want to stick with an Intel CPU and that does not blow the budget. The P3's are much better performers than the Celerons. Most people in these forums who use Cele's overclock them - i.e., they buy a 566 and run it at maybe 850 - which still is about the same performance-wise as a P3 600E. A non-overclocked Cele is very slow!
You might want to change tracks and consider an AMD CPU instead of an Intel. The new AMD Duron CPU's are much better performers than the Celerons, but cost about the same and are cheaper than the P3's. You can later replace the Duron with an AMD new Athlon/Thunderbird CPU (they're interchangeable) for a performance increase. These new AMD systems are just coming on the market and you may have to shop around for them - but that's easy as pie on the web.
The pecking order of CPU's in most apps is as follows, when comparing CPU's of similar rated speed (MHz): the AMD new Athlon aka Thunderbird is probably fastest and is cheaper than the Intel Pentium III Coppermine which performs a tad slower than the Tbird; the AMD Duron is slower than the Coppermine or Tbird but is cheaper than those CPU's and can be upgraded later by replacing it with a Tbird; the Celeron is the slowest of all and may or may not be cheapest. You will also run into the old Athlon, Celerons like the 533 or slower, and the Pentium III Katmai's - I would avoid them all.
The easiest way to not go wrong and avoid getting very confused when you are shopping is just to look for an AMD Duron CPU that is as fast as fits your budget - there are a very confusing array of Pentium III and old/new Athlon CPU's out there, believe you me. And the Duron is a great performer for the money. To see what I mean about confusing CPU's see:

As for motherboards, Tyan is a very reliable maker. Unfortunately their boards are almost entirely for Intel CPU's, and they do not make a mobo yet for the Duron or Tbird. If you are going to stick with that Tyan see

Instead, take a look at AnandTech's monthly Buyer's Guides. Each month they have a High End Systems Guide and a Value Systems Guide outlining numerous different configurations for different purposes and budgets. Print them out and read them if you like - you'll learn a lot. Note that the Guides won't recommend components that are not yet quite on the market, although they may mention them. You can put a lot of faith in the recommendations of AnandTech, IMO. Here are the latest Guides that I?ve seen that are applicable to you:

Also, for internet surfing high speed access like cable or DSL is very nice if it is available and suits your budget - it may be better than a faster CPU in practice, since your dial-up modem becomes the real bottleneck. On this topic, when you are getting a modem try to avoid a software modem, sometimes referred to as a 'Winmodem.' Most modems that go in a PCI slot are software modems, and if the box says 'requires Windows' then it's surely a s/ware modem. You want a hardware modem, and I believe most modems that fit an ISA slot or that are external modems are hardware modems. Software modems use your CPU to do some of their work, slowing the PC - h/ware modems don't.
P.S.
As was indicated 64 MB of PC133 SDRAM should be adequate for Windows 98. As for your hard drive you should try to get one that has a 7200 rpm speed if it suits your budget maybe a Western Digital Expert - this is better than 5400 rpm. The CPU, motherboard, RAM, and hard drive are the heart of any system, of course.
