So I've been hunting for the best Pentium 4 computer that I could find for Windows 98/XP retrogaming (my priority) and multimedia (particularly DVD playback). What I've found is this one particular computer, which is the Dell Optiplex GX260 from 2002 (yes, 2002 is my favorite year for computing):
It has the following specifications:
2.4GHz Intel Pentium 4 "Northwood" processor
512MB of system RAM
ATI® Radeon™ 7500 graphics card with 32MB VRAM (plus S-Video output)
Integrated AC'97 audio chip
Integrated Intel Pro/1000 MT Network chip
CD-ROM drive
Here are my plans that I'm going to turn it into "the ultimate 2002 multimedia (and gaming) PC" (once I bought that computer):
Install a 120GB 3.5" IDE hard drive and install Windows 98SE and XP on the 120GB IDE hard drive, plus install the drivers (except for the ATi Radeon 7500 graphics card) on both OSes.
Replace the CD drive with an IDE DVD drive. (or option 2: use an external USB DVD drive, but it will only work on Windows XP)
Replace the ATI® Radeon™ 7500 graphics card with a Leadtek GeForce4 Ti4400 (with 128MB of SGRAM, plus S-Video out)
And last, but not least, install the Linksys WMP54 PCI WiFi card to have Wi-Fi connectivity.
