This is gonna be a mess to keep straight, I'm a year back and forth all over the place when trying to remember when I had things... and yeah lots of overlapping stuff, the chronology is a tangle.
CPU
i) Z80 4mhz Various ZX Spectrum 48K models from 1982
iia) 68020 14Mhz Amiga 1200 early 1993, iib) 8Mhz 8086 Amstrad PC1640 iic) Amstrad PC1512 <<< '93 junk rescue/rebuilds first IBM PC architecture PCs
iiia) 8088 4.77Mhz IBM XT 5160 first "proper" PC iiib) that I gutted and put a AMD 386sx40 motherboard into.
iv) 386sx40 recased 4MB RAM 94ish
v) Cyrix 5x86 100GP oc 120x2 early 96 (and at the same time 3 or 4 junk build 486 machines)
via) P100 vib) upgraded to 6x86 PR166 early 99 <<< new wife's box at time
vii) AMD K6-266 oc 333 late 99
viii) AMD K6-400 oc 450 2000ish
ix) AMD XP-1800 oc 1700 late 2002?
x) AMD XP-1700 TbredA oc 1800 (Kinda sucked 🤣 ) 2003ish
xi) AMD Duron Applebred 1600? oc 2400 (didn't suck) 2005ish
xii) AMD Turion64 ML-32 1800Mhz 2006ish
xiii) AMD X2 5600 2010?
xiv) AMD Phenom X3 2012
xv) Core i5 3337u 2013
xvi) Core 2 quad 6600 2015ish
xvii) ??? still pounding the snot out of i5, core2s, atoms, a turionX2 and other random crap
Motherboards
i) Revision 2 to 6b Sinclair.
iia) Revision 1B I think A1200 stock amiga. iib) Amstrad stock PC1640 iic) Amstrad stock PC1512 upgraded to 640k
iiia) IBM 5160 stock motherboard 256KB version.
iv) one of the tiny 386sx AT boards, only an inch or so longer than ISA slot length, 4 30 pin, 6? ISA, not sure of manuf, Trigem???
v) Bektronic V439 with UMC chipset, for long time I thought it was an Amptron PM6900 variant.
via/b) 430FX chipset AT board, forgotten manufacturer, wasn't a top name. PCI/ISA
vii/viii) Octeck Rhino 20+ try and dig that one out 🤣 430TX PCI/ISA/SIMM/SDRAM
ix/x) Gigabyte GA7VRX KT333 if you find one, cast it into the fires of mount doom.
xi) Abit KG7-lite AMD 761 chipset and hella fast with tweaks, ran DDR/FSB at 175+. Find a KG7 model and recap it.
xii) Compaq notebook system. S754, unknown, ATI Xpress200?.
xiii/xiv) ECS MCP6100PM-AM I think, integrated Nforce type deally.
xv) Gateway notebook system NE57 series.
xvi) XFX 750i SLI something or other s775.
xvii) seeking next victim, weird assortment in current use.
Video
i) Stock Spectrum 8 color, 255 color in artifact mode (Very very seldom used, 3D Ant Attack only example I know of)
iia) Amiga AGA chipset iib) mono, herc, CGA and Amstrad is special modes on board. iic) ditto with EGA
iiia/b) Initially only a stock IBM mono text and LPT card, later a multimode card used mainly with Hercules mono, CGA sorta worked on one PAL monitor but was garish and rolled.
iv) Chips and Technologies VGA card with 256kB, I thought it was a turkey at the time, but in comparison with other ISA VGA, midrange.
v) Cirrus logic 5428 and later 5429 VLB boards with 1 to 2MB
vi) Not remembering well PCI 1MB basic, maybe a Trio.
vii/viii) Started off with a TGUI9680 with 2MB installed, got a Voodoo3 2000 PCI on an outpost.com voucher deal (While it was also on sale $50 out of pocket total w00t)
ix/x) MSI Gf3ti200 128MB ... I thought the 128MB was futureproofing, but the GF4 came out in a month and killed it before they'd finished tuning up the drivers.
xi) GF4ti4200 forgotten make I wanna say Gainward??, overclocked VERY well, past 4600, got over 18k 3dm2k1 on that system.
xii) ATI x300 onboard deally.
xiii/xiv) inbuilt Geforce 6150 but used Geforce 9600GT and Radeon HD4650 in it, not sure which order, has 9600 in at the moment, think for it's video codecs.
xv) Intel HD4000
xvi) oh man what hasn't this had in it? HD4850s were first I think, followed by HD6750s, then HD5850s.. upgrades, sidegrades we go every which way here.
xvii) seeking next victim, weird assortment in current use... gotta put the 650Ti and R9 285 in something though.
Sound
i) Spectrum beeper.
iia) Amiga 4 channel stereo sound
iib/c/iiia/b/iv) PC Squeaker... with the exception that the Amstrads had some sort of improved version, amplified and filtered with a volume knob, don't think there was any synth hardware.
v) Aztech 16 bit something or other came in multimedia kit from RadioShack/Tandy did SB pro2 and WSS/MSS
vi) Some weird crystal chipset monstrosity with integrated 14.4k voice modem. I keep thinking Mozart was in the name or something.
vii/viii) Had soundblaster 32 in heyday, not sure if I started with onboard or ess or went soundless a month or two.
ix/x) Onboard sound was adequate, realtek chipset?
xi) Think I was using an ALS4000 in this one, may have has a SB16 PCI of some type at some point.
xii/xiii/xiv/xv/xvi) whatever onboard is onboard.
xvii) Newest separate soundcard is 17 year old SB live value type thing, just got, maybe going into something modernish soon.
Cases
Whatever was stock to pre-man systems, whatever was cheap to the ones I built, serious lot of no-name cases, 386to586 was a minitower, the name top power comes up a lot for cases of that type, the pentium had a fat midi, generic, AXP had cheap beige midis, the c2Q is in some corsair, with the PSU bottom mounted, radiator mounting space up top, front looks like a pile of drive bays. Approach to case aesthetics=utilitarian.
Edit: I might be a liar, that might be a Cooler Master case, not a Corsair.
Cooling
Nothing super fancy, nothing before the 5x86 needed it, but when I got that, it had the green bonded sink, but I bought a 486 blower sink with the clips molded into the fan, put the supplied sink aside and clipped that on top of my 5x86. I had found out in electronics pottering that big transistors etc should be mounted to a sink with heatsink compound, so all the junk 486 machines and everything I put together from then on, got the RS components zinc oxide compound on them... until the AXP era when I modernised to AS3 and similar. Socket 7 and K6-2 got sinks on them bought with a kid of mental bigness/cheapness index, there was very little action or apparent common sense from what you'd now think of as the main brands until 99 or 00 when serious attention to cooling for stock speeds was required. Whereas I went for overkill cooling for overclock potential previously. Then the AXPs got first a Volcano 6cu+ and then an AX7 with tornado fan, this was replaced with a higher pressure blower and coolermaster similar to volcano in the 2.4ghz rig. IDK what I've been using lately mostly generic stuff, mix and match with fans until I'm happyish with temps. Cases had 80mm panaflows then 120mm for the coolermaster.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
