Monitor not included (as I already have a dandy KDS 19 inch CRT)...
... I just built (a couple of days ago, as a matter of fact, and my first ever, at that [all because HP, Compaq, Dell, Gateway, Sony, and e-Machines won't include extra bays nowadays in the cases of their more affordable machines]!) a new rig and in an older design Codegen steel case my brother in law gave me , after I took out the included 300 nominal watt power supply:
AMD Athlon 64 3000+ cpu chip (power/cost ratio heavily in favor of AMD over Intel)
MSI K8T Neo FIS2R motherboard
two sticks of 512 Mb Kingston ValueRAM DDR 400 RAM
ATI Radeon 9700 Pro w/128 MB RAM
Western Digital 120 Gb SATA HD
IOMagic 52x Combo DVD-ROM/CD-RW drive
Iomega 250 Mb Zip drive
Antec True Power 430 W power supply
and of course, the obligatory FDD, this one by Samsung
(The only problem with any new system is that SFC1 runs buggily on them. Oh well, at least there's OP, EAW, and SFC3, still.)
Now, I'll agree with Iceman that Newegg is an excellent source to get comp parts. I got most of the major components there. But I found on Yahoo shopping's site, an online store called Qtek:
http://store.yahoo.com/qtek/Some prices on some items are quite good and if you're looking for an affordable, more old fashioned clicky keyboard (Focus FK-2001; requires AT-PS2 adaptor) like I was, then it's not a bad site to look into. They even gave me free shipping on a backordered item and it came only a couple of days later. I got some smaller items there, like the floppy, Zip drive, keyboard, case fans, and a laser toner cartridge.
Also, MicroCenter is pretty good on various items if they have a sale on them. I got my Radeon 9700 there for half of its original list price (when it first came out) and the DVD/CD drive for just a few tens of bucks. If there isn't one in your state, they are online at:
http://www.microcenter.com/And don't snub Best Buy! When they have a sale on HDs or video cards or DVD or CD drives, it can be pretty good, too. Again, if no store near you:
http://www.bestbuy.com/Incidentally, my new machine DOES NOT HAVE the "de rigueur de jour" (at least for the kiddie set) blinky LEDs all over the place nor the braggart's plastic window on my side panel. I'll only suffer LEDs (and red ones at that) on my old HP calculator. Besides, one day, even 400W may not be enough (oh the electric bill!) and I don't want even a microamp to get wasted on a nonessential as a cosmetic light. But I'll consider putting the AMD sticker on it somewhere.
