I decided to "go back" so to speak and build up a Windows XP PC … well actually two! One for early to mid 2000s games and one that is amped up to the Max for XP (without messing around with custom GPU drivers too much).
What brought that on was that a)I didn't manage to get Switch 2 pre-order in and b) I was watching some retro PC YouTubers and couple of them had videos from a year or two/three ago talking about XP builds. And I thought to myself that this is something which could be fun considering number of games I have on GoG, physical PC games I have been picking up on the cheap (surprisingly mint 2000s full game cases of great games go for barely anything) and abandonware.
So I started to dig through my bins with old hardware and found bunch of motherboards, RAM, smaller / older SSDs and HDs, fans, CPU coolers and so on. I also had some cases but didn't really like most of them so picked up that Fractal case from Microcenter. And I did dig up my old Boston Acoustics Speaker/Sub set as well.
I still needed a CPU for my "mid-2000s" XP, with Intel Core 2 Quad QX9650 being the best bang for $ (~$50), as well as a bit beefier GPU in 8800GTX (also around $50, still pondering if I want SLI) as I couldn't find my old 8800GT that I used to have... or my core 2 quad that I also used to have,

. I am going to throw 2 x 2GB of RAM into this, couple older 60GB SSDs in RAID-1 for OS and a 500GB SATA SSD for game drive.
And for my "super" XP computer I needed a proper GPU. I am going to use i7-3770K, board and 8GB of RAM .. but I picked up OG Nvidia Titan 6GB as that can run on XP ($65 or so) and XFS Radeon HD 6970 ($40 or so) as it does better with some of resolution scaling with AMD drivers vs Nvidia. And finally I got three different monitors for all of this. One older Dell 24" 1920 x 1200 60hz monitor (found locally for about $40ish) and couple 1280 x 1024 monitors (Acer and Viewsonic with 75hz refresh, about $30-40 each). I had couple SSDs and a 4TB HD to use for this one as well. And its going into the Fractal case.
So in summary, I spent $115 for a case, $50 for a CPU, $160 for 3 GPUs and $130 for the monitors. ~$450 for everything which is the same price as Switch 2!

Going to play through GTA IV, Fear 1&2, Crysis, bunch of Star Wars games, Need for Speed 2, Outrun and more as it was meant to be.
The only thing I am still considering is getting a CRT, but its too much of a pain to maintain and finding a good condition nice CRT monitor of say 20-21" is not a trivial task.
Edit: I might redo the older PC into Win98/ME build at some point, but Win98 was a bit of a pain, lol.
