Err... Eesh... Well I have had an awful lot of PC's in a relatively short space of time, I used to buy and sell bits and pieces like nobodies business, but now ive cut down a fair amount.
I currently have just my main desktop PC:
i5 2500K @4.6GHz (1.377v) w' Antec Kuhler 620 + Venom Viper push/pull
ASRock Extreme 4 Gen 3 Z68
8GB Vengeance Black + 16GB Patriot Signature (9-9-9-24 1600MHz 1.5v)
GTX660 OC Twin Frozr III (1137, 6320)
40GB OCZ Vertex 2
1TB SpinPoint F3 + 2TB WDC Green
Asus Xonar DS
OCZ ModXstream Pro 700W
Lancool PC-K62 Dragon Lord
My server/home LAN/folding system:
Phenom II 955BE w' Zalman CNPS10X Quiet
Gigabyte 78LMT-USB3 AM3+
8GB TeamGroup Elite 1600MHz
GTX460 XLR8 Enthusiast Edition (stock clocks, 0.8v)
500GB SpinPoint F3
OCZ CoreXstream 500W
Xigmatek Helios
My laptop:
AMD Turion II Ultra M620 @ 2.5GHz
4GB Hynix 800MHz DDR2
Radeon HD4530M 512MB
320GB Toshiba 7200RPM
IDT HD Audio
Old system that I cant bring myself to get rid of:
Pentium 4 Northwood 2.8 @ 3.1GHz w' Coolermaster Aquagate Viva watercooling
AOpen AX4PER-GN skt478
2GB Zeppelin DDR400
Radeon 9550 256MB (did have a 6800GT 512MB but it died

)
80GB WD800 + 250GB WD2500
EZ-Cool 400W
- unsure what the case is -
I have boxes upon boxes of stuff that needs shifting though. Ive had Athlon 64 systems, Core 2 Duo systems, Core Duo systems, Sempron systems, Athlon II systems, Xeon servers, Celeron D systems, Pentium D systems, a VIA Cyrix III system, a Pentium 166MHz system and an 80286 system... (I am probably missing some...)
Looking to replace a-lot of the parts in my main PC very soon. (motherboard, SSD, PSU, RAM, fitting a custom loop, custom spraying the case, and so on)
