> The x220 I've never seen dip below $100 with 4GB RAM and a hard disk or at least a caddy. ThinkPad caddys are dirt cheap. You can buy third party compatible caddys for under $10. [0] In terms of a laptop with a reasonable build quality that includes a TPM, pretty much any corporate laptop will suffice. X220's command a premium because they're ThinkPads. If you look at other options, something like the Dell E6220, which is from the same generation as the X220, can be purchased used for around $100. [1] They don't support coreboot, but they're otherwise reliable machines. The Dell UEFI implementation supports only allowing signed updates and SecureBoot. Depending on your threat model this might be enough for you. > You can buy an ebay business-grade laptop with TPM for 40 bucks USD readily You'll have to buy something older than the E6220 mentioned above, but the Dell E6400 is available for $40. [2] That will have an integrated TPM. [0] http://www.ebay.com/itm/Lenovo-Thinkpad-X220-X220i-Hard-Drive-Caddy-Rail-Kit-/231104104576 http://www.ebay.com/itm/Lenovo-Thinkpad-X220-X220i-Hard-Driv...
