I am selling these items for what I'd like to think is pretty cheap, but may only appeal to a certain segment of the community. I could sell them on eBay, but I'd prefer to do it on here to help out Bitcoins. If you would like to make an offer, feel free to. Shipping is US only and includes USPS Priority shipping unless otherwise noted.
Creative SoundBlaster X-Fi XtremeGamer (SB0730) -- 1.75 BTC shipped. This card is not like the budget XtremeAudio card and has the legit high-end X-Fi hardware. It is a low profile card, so it would do well in a HTPC computer; however, I do not have the low profile faceplate, so you would have to mod it (not hard). You should know that Creative drivers suck and there are some issues with Windows 7, although I was able to get it working as it should in the end.
120GB Western Digital Caviar SE IDE drive w/ 8mb cache -- 1.2 BTC shipped. May be good for someone looking to cut costs in a mining rig? It works well and I've never had a problem with it. Was a bit loud in my HTPC though. The serial number has never been used, so you'd be able to get WD Loyalty pricing with it.
AMD Athlon 2100+ (overclockable to 2.3+GHz stable), Abit NF7-S, 1.5GB OCZ DDR, and SLK-800 all-copper heatsink -- 2.5 BTC shipped (may ship UPS Ground or similar depending on prices). Supports SATA with RAID 0/1. Perhaps it would make a good pfSense firewall, budget file server, web server, or whatever. Learn Linux with it. Use whole drive encryption to keep certain things safe without having to slow down your main PC. Only thing wrong with it is that the fan on the northbridge isn't working, but this doesn't really matter. I will include an extra chipset HSF in case you need it.
I may have some other things up soon, so check back if you like older PC parts. Thanks
