They say big things come in small packages, and that's precisely the marketing angle Lian Li has taken with its small form factor cases. Being a mini chassis, the company's new PC-A04 only accepts micro-ATX or mini-ITX motherboards, but it can still hold up to seven 3.5-inch drives and a high-end graphics card -- just like the PC-V354 we reviewed in October. The PC-A04 has two removable hard drive cages that can be mounted facing the left, right, or back. As we saw with the Mini Q PC-V354, this offers extreme flexibility. You can use the enclosure for an HTPC or a home server with tons of storage, or you can remove one of the cages to provide clearance for video cards measuring up to 370mm long. Externally, the PC-A04 greatly resembles the PC-V354, but they have different dimensions. The former is (W) 188mm x (H) 386mm x (D) 460mm, while the latter measures (W) 245mm x (H) 320mm x (D) 420mm. The PC-A04's additional height can mostly be attributed to its extra 5.25-inch bay. Both weigh about the same at 4.1kg versus 4.17kg.
